Answer:

About 153.94 units^2

Step-by-step explanation:

The area of a circle can be found using:

[tex]a=\pi r^{2}[/tex]

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

[tex]a=\pi 7^2[/tex]

Solve the exponent

[tex]a=\pi 49[/tex]

Multiply

a=153.938040026

Rounded to the nearest hundreth

a=153.94

So, the area is about 153.94 units^2
