someone please help:
explain what (pi)(r^2) and h represent in terms of the cylinder. Then explain how this information is used to find the formula for the volume of a half sphere, 2/3*pi*r^2*r. Then explain how you use this formula to get the formula 4/3*pi*r^3 for the volume of a sphere.
(I don't really get what this question is asking?)
ps: drawing in the comments if you need it
