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 )
