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!
The answer is A, because 2.54 times 20 equals 50.8
337.44 is the exact answer. Happy to help.
