Question

Find the area of the circle a-21.98 m2 b-153.86 m2 c-14 m2 d-483.13 m2

Answer 1

Answer:

B) $153.86 meters^{2}$

Step-by-step explanation:

The formula for the area of a circle is : $\pi *radius^{2}$

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.

$\pi *7^{2} =153.86 meters^{2}$

Answer 2

The answer is a because of 2cm being the radius
