Question

Find the volume of the sphere shown to the right. Give an answer in terms of and rounded to the nearest cubic unit.

Answer 1

36π in³ , ≈ 113 in³

Explanation:

the volume (V) of a sphere is calculated as

V =
`(4)/(3)` πr³ ( r is the radius )

given diameter = 6 , then r = 6 ÷ 2 = 3

V =
`(4)/(3)` π × 3³

=
`(4)/(3)` π × 27

= 4π × 9

= 36π in³ ← exact value

≈ 113 in³ ← approximate volume
