An orange has a diameter of 3 inches. Evaluate the volume of one orange. (π = 3.14)
a. 9.42 in3
b. 113.04 in3
c. 28.26 in3
d. 14.13 in3
d. To determine the volume of a sphere, use the formula Volume = 4 πr3. Volume = 4 (3.14)(1.5)3 = 14.13 in3. If you select a, you squared the radius instead of cubing the radius. If you select b, you cubed the diameter instead of the radius. If you select c, you found the surface area of the sphere, not the volume.
