Question

What the area of a circle with the radius of 7

Answer 1

About 153.94 units^2

Explanation:

The area of a circle can be found using:

`a=\pi r^(2)`

We know r, or the radius is 7, so we can substitute that in

`a=\pi 7^2`

Solve the exponent

`a=\pi 49`

Multiply

a=153.938040026

Rounded to the nearest hundreth

a=153.94

So, the area is about 153.94 units^2
