Cylinders and Spheres

I've been bashing my brain to solve this problem for days, but I don't know how to solve it.  It seems really easy though.  Please help:

The volume of a cylinder is 60 cubic centimeters. What is the number of cubic centimeters in the volume of the sphere it circumscribes?

Hi;


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Do you see how it is derived?

Re: Cylinders and Spheres

I see it now

I also need help on this problem:
A water-filled spherical balloon lands on a sidewalk, momentarily flattening to a hemisphere. The ratio of the radius of the spherical balloon to the radius of the hemisphere can be expressed in the form sqrt[3]{a} for some real number a. Compute a.

Hi;

I am not getting any answer close to that at all. Probably means I do not even understand the question.
