Question
A farmer wants to know how much corn he is going to sell at the end of the season. He stores the corn in a silo, which is in the shape of a right circular cylinder. If the height is 40 feet, and the diameter is 15 feet, what is the volume? Use 3.14 for π .
First, we need to find the radius of the cylinder. Since the diameter is given as 15 feet, the radius is half of that, which is 15/2 = 7.5 feet.
Next, we can use the formula for the volume of a cylinder:
V = πr^2h
Plugging in the values we have:
V = 3.14 * (7.5)^2 * 40
V = 3.14 * 56.25 * 40
V = 3.14 * 2250
V = 7065 cubic feet
Therefore, the volume of the silo is 7065 cubic feet.
