Answer:

B) [tex]153.86 meters^{2}[/tex]

Step-by-step explanation:

The formula for the area of a circle is : [tex]\pi *radius^{2}[/tex]

The radius of a circle is the length from one side to the centre.

To work this out you would have to multiply pi by the radius of 7 squared, this gives you 153.94, however if using pi as in 3.14, then the answer is 153.86.

1) Multiply pi by 7 squared.

[tex]\pi *7^{2} =153.86 meters^{2}[/tex]

The answer is a because of 2cm being the radius
