What happens to the volume of a cylinder if the radius is doubled?

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 cm³ and a height of 5 cm, what is the radius?

Back

Radius = √(Volume / (πh)) = √(100 cm³ / (π * 5 cm)) ≈ 2.52 cm.
