Question

What is the volume of a cone that has a base with a radius of 4 inches and a height of 12 inches?

Answer 1

Answer:
`201.06\ in^3`

Explanation:

The volume of a cone can be calculated with this formula:

`V=(1)/(3)\pi r^2h`

Where "r" is the radius and "h" is the height.

In this case you know that this cone has a base with a radius of 4 inches and a height of 12 inches. Then:

`r=4\ in\\h=12\ in`

So, in order to calculate its volume, you must substitute these values into the formula. Then:

`V=(1)/(3)\pi (4\ in)^2(12\ in)\\\\V=201.06\ in^3`

Answer 2

The volume of given cone = 200.96 inches³

Explanation:

Points to remember

Volume of cone =(1/3) πr²h

Where 'r' is the radius and 'h' is the height of the cone

To find the volume of cone

Here r = 4 inches and h = 12 inches

Volume = (1/3)πr²h

= (1/3) * 3.14 * 4² *12

= 200.96 inches²

Therefore the volume of given cone = 200.96 inches³
