Question

A cone has a diameter of 8 centimeters and a height that is 4 times the diameter. Using 3.14 for pl, which of the following can be used to calculate

volume of the cone?

Answer 1

Volume of cone is
`539.89 \ cm^3`.

Explanation:

Given:

Diameter of Cone = 8 cm

Now we know that radius is half of diameter.

radius =
`(1)/(2)*8 =4\ cm`

Also Given:

height that is 4 times the diameter.

So we can say that;

Height =
`4*8 =32\ cm`

We need to find the volume of the cone.

Solution:

Now we know that Volume of the cone is given by one third times π times square of radius times height.

framing in equation form we get;

Volume of the cone =
`(1)/(3)\pi r^2h= (1)/(3) \pi * (4)^2* 32 =539.89 \ cm^3`

Hence Volume of cone is
`539.89 \ cm^3`.
