Answer to Question #11875 in Geometry for Maranda
V = 4/3·pi·(D/2)³ = 4/3·pi·(20/2)³ = 4/3·pi·1000 feet³.
So, a tower contains
3/4·V = 3/4·4/3·pi·1000 = 1000·pi ≈ 1000·3.143 = 3143 feet³
of water when it is 3/4 full.

volume of spherical water tower = (4/3)*pi*radius^3 ,where radius=10 feet
= 4190.67 cubic feet
now contained water (in cubic feet) when it is 3/4 full = (3/4) * 4190.67 = 3143 cubic feet (approx.)
