The volume of the silo that consist of a hemisphere and a cylinder is calculated as: 52,281.0 m³.
How to find the volume of the silo?
The volume of the silo = volume of cylinder + volume of hemisphere
The volume of the silo = πr²h + 2/3πr³
From the image, we are given:
radius of cylinder (r) = 30/2 = 15 m
radius of the hemisphere (r) = 30/2 = 15 m
height of the cylinder (h) = 79 - 15 = 64 m
π = 3.14
Plug in the values:
The volume of the silo = 3.14 * 15² * 64 + 2/3 * 3.14 * 15³
The volume of the silo = 45,216 + 7,065
The volume of the silo = 52,281.0 m³
