Question

A tower has a cone-shaped attic. The diameter of the attic is 18 ft and its height is 18 ft.

What is the volume of the space in the attic?



Enter your answer as a decimal in the box. Use 3.14 for pi

Answer 1

Volume of a cone is: PI x r^2 X h/3

R = 1/2 x diameter = 1/2 x 18 = 9 ft.

H = 18 ft.

Volume = 3.14 x 9^2 x 18/3

Volume = 3.14 x 81 x 6

Volume = 3.14 x 486

Volume = 1526.04 cubic feet.
