Question

If h= 15 units and r= 5 units, what is the volume of the cone shown above? Use 3.14 for pi

Answer 1

$\begin{matrix} V\\\\=\pi r^2\left(\frac{h}{3}\right)\\\\=\pi \left(5\right)^2\left(\frac{15}{3}\right)\\\\=25\pi \left(5\right)\\\\=125\pi \\\\\approx 392.69908\\\\\approx \mathbf{392.7\:units^3} \end{matrix}$
