Question

What is the exact volume
?

Answer 1

see explanation

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 =
`(4)/(3)` πr³ ← r is the radius, thus

V =
`(4)/(3)` π × 3³

=
`(4)/(3)` × 27π = 36π m³
