Answer:
r = 5.9984789350480924657633167413961 yards
Explanation:
h = 4 yards
V = 452.16 yards Cubed (cubic yards)
V = π
h
452.16 = π
*4
divide by pi and 4 and you get approx 35.98
35.981 =

the square root of 35.98 is approx 5.9984789350480924657633167413961
which is equal to r, or the radius
r = 5.9984789350480924657633167413961 yards
