How many 1 inch balls will a 10 inch sphere hold?


volume of 10" sphere is 1000 ties that of a 1" sphere (volume scales as the cube of linear dimension). The close packed fill-factor for spheres is 0.74 (see eg http://en.wikipedia.org/wiki/Close-packing_of_spheres). Thus you will get LESS THAN 740 1" spheres into a 10" sphere (quick calculation neglecting edge effects, which is why 740 is only a bound, not the actual number)

Is it possible to enter and save a formulae to this calculator and if so can you please give instructions on how to do so and how to retrieve the formulae after it is entered thankyou


Yes, it si possible, but as a teacher I am wary of teaching anybody how to cheat. No reflexion on you, If your teacher wanted to show you how to store formulas s/he would have done so. Awfully sorry.
However, nobody nor nothing prevents you from reading the manual and learning how you do it. That is a skill worth having.

How do i use the TI-30XA for algebra


Well it depends on what you are wanting to do.
  1. Graphing- get a graphing calculator!
  2. logistics- for log base 10, just divide the number by 10.
  3. ln- divide the # by the number e (roughly 2.72)
  4. sine, cosine, and tangent- there should be a "SIN", "COS", and "TAN" button, if not the ratio for each, respectivly is opposite/hypotnenuse, adjacent/hypoteneuse, and opposite/adjacent. (The opp/adj being side opp or adj of angle you are doing)
  5. Just Ask your teacher!

Stuck in Hexadecimal!


Try removing the batteries, and cover any solar displays - or lock in a drawer fro a couple of days.

This may help it revert to it's standard start up routine.

Hope this assists. I cannot find a manual listed for these.
