Evaluate the volume of a ball, Mathematics

Assignment Help:

Evaluate the volume of a ball whose radius is 4 inches? Round to the nearest inch. (π = 3.14)

a. 201 in³

b. 268 in³

c. 804 in³

d. 33 in³

b. The volume of a sphere is πr³. Using the dimensions given, volume = 4 x (3.14)(4)3 or 267.9. Rounding this answer to the nearest inch is 268 in³. If you select a, you found the surface area rather than volume. If you select c, you miscalculated surface area by using the diameter.
