Answer 1

Option C- 314 in²

Explanation:

Given : Radius of the circle r=10 inches

To find : What is the area of a circle ?

Solution :

Formula of area of circle

`A=\pi r^2`

Where A is area , r is radius= 10 and
`\pi =3.14` (given)

Put value in the formula we get,

`A=3.14* 10^2`

`A=3.14* 100`

`A=314 in^2`

Therefore, Area of circle is 314 square inches.

So, Option C is correct.
