Question

What is the approximate volume of the cone?

Use 3.14 for π.

A 1272 cm³

B 2120 cm³

C 4239 cm³

D 6359 cm³

Answer 1

`\textit{Volume of a Cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=15\\ h=9 \end{cases}\implies V=\cfrac{\pi (15)^2(9)}{3} \\\\\\ V=675\pi \implies V\approx 2120~cm^3`
