A cone has a height of 8 yards and a radius of 3 yards. What is its volume?

alina1380 [7]

<h3>Given:</h3>

h= 8 yd
r= 3 yd

h= Height
r= Radius

The volume of the given cone.

<h3>Solution:</h3>

$\large\boxed{Formula:V= \frac{1}{3}\pi{r}^{2}h}$

$\large\boxed{\red \pi \red = \red 3 \red . \red 1 \red 4}$

Let's solve!

Substitute the values according to the formula.

$V= \frac{1}{3}×3.14×{3}^{2}×8$

$\large\boxed{V= 75.36 \: {yd}^{3}}$

<u>Therefore, the volume of the given cone is 75.36 cubic yards.</u>
