Answer:
V ≈ 18.0 m³
Step-by-step explanation:
The volume (V) of a cone is calculated as
• V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the perpendicular height )
here r = 7 m, h = 14 m and using π ≈ 3.14 , then
V ≈ [tex]\frac{1}{3}[/tex] × 3.14 × 7² × 14
≈ [tex]\frac{1}{3}[/tex] × 3.14 × 49 × 14
≈ [tex]\frac{1}{3}[/tex] × 3.14 ×686
≈ [tex]\frac{3.14(686)}{3}[/tex]
≈ [tex]\frac{2154.04}{3}[/tex]
≈ 18.0 m³ ( to the nearest tenth )
