A cone has a base area of 78.5 cm² and height 12 cm. What is its volume? (Use π ≈ 3.14)

Question

Accepted Answer

1. Use the cone volume formula: $V=	frac{1}{3}Bh$, where $B$ is base area and $h$ is height.
2. Substitute $B=78.5$ cm$^2$ and $h=12$ cm: $V=	frac{1}{3}	imes78.5	imes12$.
3. Compute $	frac{1}{3}	imes12=4$, so $V=78.5	imes4=314	ext{ cm}^3$.
