3≈33.51032 =33.51 is the answer

Short Answer: 33.5cm3. 

Longer Answer: The formula for volume of a sphere is ( 4 pi radius^3) / 3. So, when the radius is 2cm, then it would be ( 4 3.14 2^3) / 3. We have to do the exponents first, so 2 ^ 3 is 2 2 2 = 8. Then, we solve the rest of the expressions within the bracket, which will give us ( 100.48 ) / 3, and that equals 33.5
