A silo consists of a right circular cylinder with a hemisphere on top.
The radius of the cylinder and of the hemisphere is 10 feet, and the height of the cylinder is 25 feet.
Which of the following is closest to the volume, in cubic feet, of the silo.
:
The formula for this
V = pi%2Ar%5E2%2Ah + 2%2F3pi%2Ar%5E3
:
V = pi%2A10%5E2%2A25 + 2%2F3pi%2A10%5E3
:
V = 7854 + 2094
:
V = 9950
