Answer:

see explanation

Step-by-step explanation:

(7)

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

V = [tex]\frac{1}{3}[/tex] × 24π = 8π ft³

(8)

(a)

V = [tex]\frac{1}{3}[/tex] × area of base × height

  = [tex]\frac{1}{3}[/tex] × π × 4² × 10

  = [tex]\frac{1}{3}[/tex] × 160π ≈ 167.6 in³ ( nearest tenth )

(b)

divide volume by 58 ( the conversion factor )

= [tex]\frac{167.6}{58}[/tex] ≈ 2.9 quarts ( nearest tenth )
