To find the volume of the whole, you will use the formula for finding the volume of a cone. V = 1/3 x r^2 x h.

You will first need to find the radius by using the information given about the circumference and the circumference formula.

C = pi x d
44 = 22/7 d
d = 14 feet.

Then use the diameter to find the radius of 7 feet.

V = 1/3 x r^2 x h
1/3 x 7^2 x 3
V = 49 cubic feet
