Answer 1

For a cylinder you need radius and height
Cone you need radius and height
Sphere you need radius.

For a cylinder you need radius and height

cone you need radius and height

sphere you need radius.

Answer 2

For the volume of a cylinder, it is volume=base times height.
For the volume of a cone, it is volume=1/3 times base times height.
For the volume of a sphere, it is volume=4/3 times pi times r^{3}
