Answer 1

see explanation

Explanation:

(7)

The volume (V) of the cone is one third the volume of the cylinder

V =
`(1)/(3)` × 24π = 8π ft³

(8)

(a)

V =
`(1)/(3)` × area of base × height

=
`(1)/(3)` × π × 4² × 10

=
`(1)/(3)` × 160π ≈ 167.6 in³ ( nearest tenth )

(b)

divide volume by 58 ( the conversion factor )

=
`(167.6)/(58)` ≈ 2.9 quarts ( nearest tenth )
