Question

I need help with my APlus...

Answer 1

V = 3617.28 in³

Explanation:

The volume ( V) of a sphere is

V =
`(4)/(3)`πr³ ← r is the radius

The volume of a hemisphere ( half of a sphere ) is therefore

V =
`(1)/(2)` ×
`(4)/(3)`πr³

=
`(2)/(3)`πr³

=
`(2)/(3)` × 3.14 × 12³

=
`(2)/(3)` × 3.14 × 1728 = 3617.28 in³

Answer 2

i think its the first option

i hope this is useful :)
