Answer:
D) V = (1/3)Bh where B = πr²
Step-by-step explanation:
The volume of a right circular cone can be calculated as

Where B is the area of the base and h is the height. The base of a circular cone is circular, so the area of the base is calculated as

Which is the area of a circle.
Therefore, the answer is
D) V = (1/3)Bh where B = πr²
