Question

Find the volume of a cone with a height of 9ft and a base diameter of 12 ft. Use the value 3.14 for n, and do not do any rounding. Be sure to include the correct unit in your answer.

Answer 1

Given:

it is given that thw height of a cone is 9 ft and base diameter is 12 ft.

Find:

we have to find the Volume of the cone.

Step-by-step explanation:

we know the volume of the cone with height h and radius r is

`V=(1)/(3)\pi r^2h`

here height (h) = 9 ft

diameter d = 12 ft

Therefore, radius r = 12/2 = 6 ft

The Volume of the cone is

`V=(1)/(3)\pi(6)^2*9=(1)/(3)*(3.14)*36*9=339.12\text{ }ft^3`

Therefore, the volume of the given cone is 339.12 ft^3
