What is the volume of a cone with a diameter of 30 feet and a hight of 60 feet

ivolga24 [154]

Answer:

4500 $\pi$ $ft^{3}$ or 4712.39 $ft^{3}$

What we need to know: The formula for the volume of a cone is: $V=\pi r^{2} \frac{h}{3}$

So we are solving for V

Step-by-step explanation:

1) Radius is half of diameter r=30/2 thus, your radius is 15

2) you then have all your variables so you can start plugging values into your equation:

r=15 h=60

$V=\pi 15^{2} \frac{60}{3} \\V=\pi (225)*(20)\\V=\pi(4500) \\V= 4500\pi$

This would be your exact answer but if you are solving for a rounded answer it would be

V~4712.39 $ft^{3}$
