unfortunately I cant manage to understand ur question
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
Add all those numbers and divide by 6 will get you 78
When one quantity increases and the other quantity increases as well, then that is a direct proportional relationship.
So the graph of this relationship is a direct proportional relationship.
Hope this helps.
BC² = 11² + 11²
BC² = 121 + 121
BC² = 242
BC = √242
BC = 11√2
Answer: 11√2
