A grain silo with the shape of a right cylinder is to be filled with corn. The diameter of the silo is 14 feet and the height is 30 feet.

Excluding the domed top, approximately how many cubic feet of corn will the silo hold? Use 3.14 forπ.

The formula for the volume of a cylinder is V = πr^2h, where r is the radius (half the diameter) and h is the height.

In this case, the diameter is 14 feet, so the radius is 7 feet. The height is 30 feet.

Plugging in these values, we get:

V = 3.14 x 7^2 x 30

V = 4615.8 cubic feet

Therefore, the silo will hold approximately 4615.8 cubic feet of corn, excluding the domed top.
