Question

Someone help meeeeeeee

Answer 1

3rd option

Explanation:

The volume (V) of a sphere is calculated as

V =
`(4)/(3)`πr³ ( r is the radius )

Given diameter = 4 then r = 4 ÷ 2 = 2 cm

V =
`(4)/(3)`π × 2³ =
`(4)/(3)`π × 8 =
`(32\pi )/(3)` cm³

combined volume =
`(32\pi )/(3)` + 20π =
`(32\pi )/(3)` +
`(60\pi )/(3)` =
`(92\pi )/(3)` cm³
