Question

The top of the silo is a hemisphere with a radius of 11 ft. The bottom of the silo is a cylinder with a height of 38 ft. How many cubic feet of grain can the silo hold? Use 3.14 for pi and round your answer to the nearest cubic foot.

Answer 1

17,224 ft^3 to nearest cubic foot.

Explanation:

Volume of grain it can hold

= volume of hemisphere + volume of the cylinder

= 1/2 * 4/3 * 3.14 * 11^3 + 3.14 * 11^2 * 38

= 2786.23 + 14437.72

= 17223.95
