Question

Find the volume of a cone with a slant height of 15 inches and a radius of 9 inches. Leave your answers in terms of π

Answer 1

Given:

height(h)=15 inches

radius(r)=9 inches

Volume of cone:

$V=\pi\times r^2\times\frac{h}{3}$$V=\pi\times9^2\times\frac{15}{3}=\pi\times81\times5$$V=\pi\times405$$V=405\pi\text{ cubic inches}$
