The depth D that a sphere of radius R would need to be filled to be P percent filled can be
calculated using the formula
-D3 + 3RD2 = 4PR. What would the depth need to be if the sphere has a radius of 4 feet and
you want the sphere to be 37 percent full? Substitute your percentage as a decimal in for P.
Type your answer to the nearest hundredth of a foot.
Give your answer to two decimal places.
