Answer:
27π in³ ≈ 84.8 in³
Explanation:
The formula for the volume of a cone is ...
V = (1/3)πr²·h
where r represents the radius of the base of the cone, and h represents its height perpendicular to the base.
The diagram shows r = 3 in, and h = 9 in. Putting these numbers into the formula, we get ...
V = (1/3)π·(3 in)²·(9 in) = 27π in³
The volume is 27π in³, about 84.8 cubic inches.
