Question

Please please help thanks!

Answer 1

V = 1436.8 in³

Explanation:

The volume (V) of a sphere is calculated as

V =
`(4)/(3)`πr³ ← where r is the radius

Here r = 7, so

V =
`(4)/(3)`π × 7³ =
`(4)/(3)`π × 343, that is

V =
`(4(343)\pi )/(3)` ≈ 1436.8 in³ ( to the nearest tenth )

Answer 2
