Answer:

The volume of the cone is 462 feet³

Explanation:

The formula of the volume of a cone is V =
(1)/(3) πr²h, where r is the radius of its base and h is its height

∵ The radius of the cone is 7 feet

r = 7 feet

∵ Its height is 9 feet

h = 9 feet

Substitute the values of r and h in the formula of the volume above

∵ V =
(1)/(3) π(7)²(9)


(1)/(3) (9) = 3

∴ V = π(49)(3)

∴ V = 147π feet³

- Simplify the answer

∴ V = 461.8141201 feet³

- Round it to the nearest cubic foot

V = 462 feet³

The volume of the cone is 462 feet³
