+56 If the hemispheres have a radius of 3 feet, how many cubic feet of water can it hold?
+129657 The volume of the two hemispheres = the volume of one sphere with the same radius =
(4/3)pi(r)^3 =
(4/3)pi (3ft) ^3 =
36pi ft^3
The volume of the cylinder separating them =
pi * r^2 * h =
pi *(3ft)^2 * (13 ft) =
117 ft^3
So.....the total volume =
pi [ 36 + 117] ft^3 =
pi [ 153] ft^3 = about 480.66 ft^3
