Step-by-step explanation:
(2)
The volume (V) of the prism is calculated as
V = area of triangular face × length
area of triangular face = 0.5 × 13 × 11 = 71.5 ft², thus
V = 71.5 × 15 = 1072.5 ft³
(3)
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex] πr³ ← r is the radius, thus
V = [tex]\frac{4}{3}[/tex] π × 3³
= [tex]\frac{4}{3}[/tex] × 27π = 36π m³
