PLEASE HELP ASAP!

The circumference of a circle is 84 cm. What is the area, in square centimeters?
Express your answer in terms of pi.

Answer 1

16π cm²

Explanation:

We know that

Circumference = 2πr

=> 8π = 2πr

=> 8 = 2r

=> 8/2 = r

=> 4 = r

Now,

Area of circle = πr²

=> π × (4)²

=> π × 16

=> 16π cm²
