Question

Answer please and explain

Answer 1

V ≈ 72 ft³

Explanation:

Given that volume (V) is calculated using

V =
`(\pi r^2h)/(3)` ( r is the base radius and h the height )

Here diameter d = 6 then r = 6 ÷ 2 = 3 and h = 8 , then

V =
`(3(3^2)(8))/(3)` ( cancel 3 on numerator/ denominator )

= 9 × 8

= 72 ft³

Answer 2

Volume of cone = 72 ft³

Explanation:

diameter = 6ft

radius = 3ft

height = 8ft

Volume of a cone =
`(\pi r^2h)/(3)`

V = (3 × 3 × 3 × 8)/3

V = 72 ft³
