➷ Formula for volume of cylinder:

$\pi r^2h$

Substitute the values in:

volume of cylinder = $\pi$(9)^2 * 13

volume of cylinder = 3308.097064

Formula for volume of cone:

$\pi r^2 \frac{h}{3}$

Substitute the values in:

volume of cone =  $\pi$(9)^2 * (8/3)

volume of cone = 678.5840132

Total volume = volume of cone + volume of cylinder

Total volume = 3986.681077

The answer is 3986.68cm^3
