The volume of a cone with base radius 4 cm and height 6 cm equals:
Answer & Solution
Correct answer: B.
1. V = (1/3) π r² h.
2. Substituting r = 4 and h = 6 gives V = (1/3) × π × 16 × 6.
3. = (1/3) × 96 π = 32 π cm³.
4. So the volume is 32 π cm³.
5. 96 π would be the cylinder volume for the same base and height.
