Question

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

Answer 1

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) (h)/(3)`

So we are solving for V

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) (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)`
