Question

A cone has a height of 6 inches and a diameter of 10 inches. What is its volume?

Use ​ ≈ 3.14 and round your answer to the nearest hundredth

Answer 1

V = 157 in³

Explanation:

the volume (V) of a cone is calculated as

V =
`(1)/(3)` πr²h ( r is the radius and h the height )

here diameter = 10 , then r = 10 ÷ 2 = 5 , then

V =
`(1)/(3)` × 3.14 × 5² × 6 ( cancel 3 and 6 by 3 )

= 3.14 × 25 × 2

= 3.14 × 50

= 157 in³
