Question

I need to find the volume

Answer 1

we know the cone has a diameter of 24, that means its radius is half that or 12.

`\textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=12\\ h=28 \end{cases}\implies V=\cfrac{\pi (12)^2(28)}{3} \\\\\\ V=1344\pi \implies V\approx 4222.30~unit^3`
