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.
Cheers,
Stephen La Rocque.
