Answer 2

Answer:

see explanation

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 = $\frac{4}{3}$ πr³ ← r is the radius, thus

V = $\frac{4}{3}$ π × 3³

   = $\frac{4}{3}$ × 27π = 36π m³
