Answer:
11 yards
Step-by-step explanation:
The volume of a cone formula is:

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:

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
Multiply 120 times .7 because you just Turn the percent into a decimal
Answer:
V≈418.88
Step-by-step explanation:
Volume formula: V=πr^2h
/3
R= radius
H= height
R= 5 ft
H= 16 ft
Formula= V=π5^2(16/3)
