The volume formula of a sphere is 4/3 Pi R^3 To figure this out, we must cube the radius (multiply 3 times). 2 x 2 x 2 = 8 (4 x 2). Now we must multiply 8 by 3.14 8 x 3.14 = 25.12 Since we have gotten those out of the way, we now have to multiply 25.12 by 4/3. 4/3 x 25.12 = 33.51 33.5 in ^3 is your answer since we used volume. Hope this helps!
