Answer 1

`315.19`

Explanation:

Given:

• Radius of the cone is 7.
• Height of the cone is 7.

To find:

The volume of a cone with a radius of 7 and a height of 7.

Solution:

Use the formula:
`V=(1)/(3)h\pi r^2`

Result:

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

`=\pi *7^2*(7)/(3)`

≈
`359.18876`

Now round to the nearest hundredth.

≈
`359.19`

Note*

Nearest hundredth is the second digit after the decimal point.
