The radius of a sphere is 3 inches. Which represents the volume of the sphere?

12 cubic inches

36 cubic inches

643 cubic inches

81 cubic inches

volume of sphere = 113.14inches³ or

36πinces³

Step-by-step explanation:

given the radius of a sphere = 3inches

volume of the sphere = ?

π = 3.14v 0r 22/7

recall, the formula for finding the volume of a sphere is given to be = 4/3 πr³

so,

volume of sphere = 4/3 πr³

volume of sphere = 4/3 * 22/7 * (3) ³

volume of sphere = 4/3 * 22/7 * 27

volume of sphere = (4 * 22 * 9) / 7

volume of sphere = 113.14inches³ or 36πinces³
