SOURCE: excel formula

the formulae for the surface area of round disc is
pi * r * r
where pi=3.14 and r =radious of disc= diametre/2

for this 1st u have 2 calculate the radious of the disc that is
180/2=90mm
then convert it to  m by dividing 1000 ,so radious=90/1000=0.09 m
finally calculate the area= 3.14 * 0.09 * 0.09=0.025434 sq metres
for 38 disc multiply 38 with the above area that is
0.025434 * 38=0.966492 sq metres

in excel 2007  u can do it more easily by going 2 formulas tab.
Under formla tab click on engineering formula and  then convert
here u can convert from mm to m
after converting use the above formula i just told u.

You could do a simple +NOW-START DATE

It would depend on the format of your start dates - i.e YY, DD/MM/YY as to the results you get.

Do want the results in years, months, days?

You sort out the formula for the surface you have to calculate then substitute the numerical values for the variables (sides, bases, heights), the constants if any (pi, etc.) an press = to get the result
Ex Square with side= 2m
Surface area=side^2
Area : 2 [X^2][=] result is 4 m^2
Area: Pi* 3[^2]=28.27 cm^2

SOURCE: the volume of the cube

Are you sure you didn't mean 27 cubic inches?

That works so cleanly to a 3" square and an answer of 54

270 gives a repeating 6.whatever. That's as close as you get in the freebies for what is likely a typo

Almost exactly the way it's written in the book.

In the LineIO mode press
3 SHIFT [xth-root] 5 0 0 0 * 3 / ( 4 * SHIFT [pi] ) ) =

In the MathIO mode press
SHIFT [xth-root] 3 right-arrow 5 0 0 0 * 3 / ( 4 * SHIFT [pi]) =

xth-root is the shifted function of the key just below and right of the big round cursor pad.
* is the multiply key
/ is the divide key
pi is the shifted function of the x10^x key in the middle of the bottom row

BTW there's no "square root" in this problem. There's a "cube root" or "third root". Square root is the second root.

Testimonial: "Thank you!! I agree that I did not want the square root. I knew how to get the cube root in but could not figure out how to put in the 3/4pi part."

### How to calculate square feet

Assume you have a rectangular area such as a room and, for example, you want to calculate the square footage area for flooring or carpet. The way to calculate a rectangular area is by measuring the length and width of your area then multiplying those two numbers together to get the area in feet squared (ft2).

### How many feet in a half acre of land?

Since acre is a measure of area and feet is a measure of distance, you need to calculate the perimeter of a lot with an area of half an acre. Here are the formulas:
1. If the lot is a square (all 4 sides of equal length), multiply the length of one side by 4, to get the # of feet required to walk a half acre piece of land.
2. If the lot is rectangle: (heightx2)+(widthx2).
3. If the lot is a triangle, add up all three sides.

### Calculate gallons of a tank

I assume the length of a side is 16 in, and the height of the prism is 23 inches.
Volume of a prism is V_prism=(Area of base)*(height of prism)
Area of base is made up of the area of the 6 equilateral triangles with sides =16 inches. The height of such triangles is given by 8*SQRT(3).
Use the Pythagorean theorem or the trigonometric ratios to find the height of each of the 6 traingles.
Area of base =6*16*(8*SQRT(3))/2 sq in
Volume =6*8*8*23*SQRT(3) cubic inches
Calculate the value in cubic inches and convert to gallons: I leave that task to you.

### I dont know how to calculate m2

Hi, a cubic metre is a measure of volume, a square metre is a measure of area. you need to know length and width as well as depth. eg; imagine a cube is 1 metre wide by 1 metre deep by 1 metre high, this is 1 cubic metre, if you sliced this cube into 10cm slices it would cover 10m2. if you sliced it into 5cm slices it would cover 20m2. I hope this helps.

### If a cube has an area of 216cm3 how do you find out its length , breadth & height

If it is a cube, length, breadth, and height are all equal. If volume (not the area) is 216 cm^3 then
V=s^3 where s is the measure of a side
s=CUBIC ROOT (216)=6
s= 6 cm

### Area of traingle with tree side

All triangles have three sides.
There are two main formulas that do not call on trigonometric ratios.
The classic one:
• 1. You need the length of a base and it corresponding height (the length of the segment perpendicular to that base and passing through the vertex (summit) opposite to that base. Area=(1/2) * (measure of the base)*(measure of the height). The base and height must be expressed in the same unit.
Heron's Formula if you have the length of the three sides. Let those measures be a, b, and c.
• Calculate the semi-perimeter p with p=(1/2)(a+b+c)
• Area=Square root of (p*(p-a)*(p-b)*(p-c))
• a, b, and c must be expressed in the same unit.

### The difference between the inner and outer surfaces of a cylindrical pipe is 88cm sq..if the height of the cylindrical pipe is 14cm and the volume is 176cm cube. Find the inner and outer radius of the...

The surface area of the outer surface is the circumference of the outside of the pipe times its length. So, if OR is the radius of the outside of the pipe and SO is the outer surface area,
SO = 2 * pi * OR * 14
Similarly, the surface area of the outer surface is SI = 2 * pi * IR *14 (if SI is the inner surface area and IR is the radius of the inside of the pipe.
The question states that the difference between the outside surface area and the inside surface area is 88 sq. cm:
SO - SI = 88 ; substituting:
(2 * pi * OR * 14) - (2 * pi * IR * 14) = 88 ; factoring
(2 * pi * 14) (OR - IR) = 88 ;dividing both sides by 2*pi*14
(OR - IR) = 88/(2 * pi) = 88/(2 * 3.14159*14) = 1.00
So, the outside radius is 1 cm more than the inside radius.

It's not clear if the volume stated is the volume of the metal in the pipe or the volume of air inside the pipe, so I will solve it both ways:
If volume of 176cc is of the air inside, the formula for this volume is 14 * pi * IR *IR
176 = 14 * 3.14159 * IR * IR ; dividing both sides by 14 * 3.14159
176/(14 * 3.14159) = IR * IR ; doing the arithmetic
4 = IR * IR ; taking the square root of both sides
sqrt(4) = IR
IR = 2 cm
substituting back into the first equation, the OR is 1cm more than the IR, so
OR = 3 cm

If volume of 176cc is of the iron in the pipe, the formula for that volume is the difference between the volume of the outside of the pipe and the volume of the inside of the pipe, or
(14 * pi * OR * OR) - (14 * pi * IR * IR) = 176 ; factoring
(14 * pi) ((OR * OR) - (IR * IR)) = 176 ; dividing both sides by 14 * pi
((OR * OR) - (IR * IR)) = 176/(14 * 3.14159) = 4
but, since OR is 1 cm more than IR (from above), we can substitute OR = IR + 1
and OR * OR = (IR + 1) * (IR + 1) = (IR*IR) + 2*IR +1
So, ((OR * OR) - (IR * IR)) = 4 becomes
(IR*IR) + 2*IR +1 - (IR*IR) = 4 ; simplifying (IRsquared - IRsquared = 0)
2*IR + 1 = 4 ; subtract 1 from both sides
2*IR = 3 ; divide both sides by 2
IR = 3/2 ;
IR = 1.5cm
OR = 2.5cm

### If i know weight of aluminium uneven surface how can i calculate surface area of same?

'Area; is Length X Width. If one square unit (feet or meters) weighs one weight unit (Lb or Gr) and your weight is 2 weight units, you would have 2 area units. You say the surface area is uneven ... using this methoud would give you an approximate area so there would be some guessing ... I would say on small areas the variataion would be minimal. Larger areas with vide variation in thickness rould be more difficult to accurately figure out.

Does this help?

### Find the surface area of awooden box whose shape

If this box is a cube, and each side is 15cm long, then each side has an area of 225 square centimeters. Since a cube has 6 sides, your cube's total surface area is 1350 square centimeters. This was a fun change from the normal question... but I don't get what you're trying to do. Thanks for the question.
