If the radius of a cylinder is doubled, how does that affect the volume?

Back

The volume increases by a factor of four, since volume is proportional to the square of the radius.

If a cylinder has a volume of 100 in³ and a height of 5 in, what is the radius?

Back

Radius = √(Volume / (πh)) = √(100 in³ / (5 inπ)) ≈ 2.52 in.
