Question

What is the volume of the cone with diameter 6 m abd height 5 m? Express your answers in terms of pi.

A. 11pi m3
B. 15pi m3
C. 22pi m3
D. 31pi m3

Answer 1

B

Explanation:

The formula for calculating the volume (V) of a cone is

V =
`(1)/(3)`πr²h

where r is the radius of the base and h is the height

here r =
`(6)/(2)` = 3 and h = 5

V =
`(1)/(3)`π × 3² × 5

=
`(1)/(3)`π × 9 × 5 = 15π m³ → B
