Kadin makes a snowman by stacking snowballs of radius 2 inches, 3 inches, and 6 inches. Assuming all his snowballs are spherical, what is the total volume of snow he uses, in cubic inches? Express your answer in terms of pi.
Total volume =
(4/3) pi ( 2^3 + 3^3 + 6^3) =
(pi ) * (4/3) ( 251) =
(1004 / 3) pi in^3
