Answer:
150.7
Step-by-step explanation:
Formula for volume of a cone = [tex]\pi r^2\frac{h}{3}[/tex]
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 )
[tex]V=(3.14)4^2\frac{9}{3} \\4^2=16\\16*3.14=50.24\\\frac{9}{3} =3\\3*50.24=150.72[/tex]
Finally we round to the nearest tenth and get that the answer is 150.7yd²
