Math CentralQuandaries & Queries


Question from Rebekah, a student:

what is the height of a hemisphere with a volume of 60 ft cubed?

Rebekah, the height of a hemisphere is its radius.

The volume of a sphere is 4/3 π r3. So the volume of a hemisphere is half of that:

V = (2 / 3) π r3.

Solve for r and then substitute in 60 for V. That's your answer.
