Question

Can someone please help me with this problem!

Answer 1

11 yards

Explanation:

The volume of a cone formula is:

`V=(1)/(3)\pi r^2 h`

Where V is the volume,

r is the radius (half of diameter)

h is the height

Given,

h = 15

V = 475.17

We find the radius (r) first by substituting given values:

`V=(1)/(3)\pi r^2 h\\475.17=(1)/(3)\pi r^2 (15)\\475.17=5\pi r^2\\r^2=30.25\\r=5.5`

The radius (r) is 5.5 yards

We need the diameter, which is DOUBLE THE RADIUS, so diameter would be:

Diameter = 5.5 * 2 = 11 yards
