Question

Find the volume of a cone with a diameter of 4.2 meters and a height of 5 meters. Leave your answers in terms of pi

Answer 1

7.35 pi meters cubed

Explanation:

The formula for the volume of a cone is V=πr^2*h/3. You substitute the values you know and then solve as normal, but don't get rid of the pi. You are left with 7.35 pi meters cubed.

Answer 2

Answer: 7.35pi meters

Explanation:

Formula to find the volume of a cone is V = (1/3) x (pi) x (r^2) x (h)

diameter = 2r

4.2 = 2r -> r = 2.1 meters

plug in the height and radius in the formula

V = (1/3) x pi x (2.1)^2 x (5)

V = 7.35pi meters
