The cone has a radius of 8 feet and a height of 12 feet. What is the volume of the cone? Leave your answer in terms of π. A.32π cubic feetB. 256π cubic feetC. 374π cubic feetD. 768π cubic feet


Given:
Cone with radius 8 feet, and height 12 feet
Recall that the formula for determining the volume of cone is
[tex]V=\frac{\pi r^2h}{3}[/tex]Given the following dimensions, substitute r = 8 ft, and h = 12 ft.
[tex]\begin{gathered} V=\frac{\pi r^{2}h}{3} \\ V=\frac{\pi(8\text{ ft})^2(12\text{ ft})}{3} \\ V=\frac{(64\text{ ft}^2)(12\text{ ft})\pi}{3} \\ V=\frac{768\pi\text{ ft}^3}{3} \\ V=256\pi\text{ ft}^3 \\ \\ \text{Therefore, the volume of the cone is }256\pi\text{ ft}^3. \end{gathered}[/tex]
