Question

Does anyone know how to do this. No one will help.

Answer 1

150.8
`yd^3`

Explanation:

I helped lol.

Have a nice day! :-)

Answer 2

150.7

Explanation:

Formula for volume of a cone =
`\pi r^2(h)/(3)`

where r = radius and h = height

We are given the diameter ( 8yds ) and the height ( 9yds )

In order to find the volume we need to find the radius

We can do this my dividing the diameter by 2 ( this is because the radius is equal to half the length of the diameter)

8/2 =4

So the radius is equal to 4yds

Now we plug in the values into the formula

( remember it says use 3.14 for π )

`V=(3.14)4^2(9)/(3) \\4^2=16\\16*3.14=50.24\\(9)/(3) =3\\3*50.24=150.72`

Finally we round to the nearest tenth and get that the answer is 150.7yd²
