The volume of a cone-shaped hole is
32 pi ft cubed .32π ft3.
If the hole is
66
ft deep, what is the radius of the hole?
Welp, we have a nice ol' cylinder altitude 66 ft . Well. The formula for cylinder volume is h * pi * r^2.
32π/ 66 = 32/66 π = 16/33 π.
The radius is square root of 16/33.
Your question is not well formatted/entered v = 32 pi or .32 pi
depth is 66 or 6 ft ?
Volume of a CONE = 1/3 pi r^2 h V = 32 pi ft3 h = 66 ft r = ?
32 pi = 1/3 66 r2
r = 2.14 ft perhaps that was 6 ft deep? then r = 7 .1 ft
