 Question 62326: I hope I'm in the right section. I have question about determining volume. Here it is: What is the volume of a sphere with a 3-mile radius? V = 4/3 x pi x r3 V = 4/3 x 3.14 x 3 (to the third power) V = 4/3 x 9.42 (to the third power) V = 12.56 mi (to the third power)Answer by Earlsdon(6287)   (Show Source): You can put this solution on YOUR website!While you have the correct formula for the volume of a sphere: your interpretation is a little off. Notice that only the radius, r, is cubed, not the nor the . Substitute r = 3 and Approx. Cubic miles.
