Question

The circumference of a circle is 50.24 centimeters. Find the area of the circle. (Use 3.14 for π.)

Answer 1

The answer is 200.96 cm^2.

2*3.14*r=50.24
=>r=50.24/6.28
=>r=8 cm

Thus area = 3.14*r*r
= 3.14*8*8
=200.96 cm^2

Answer 2

For a circle,
c=2pi R
and
A=pi R^2
so rearranging we get
A=c^2/4pi
plug in the values
A=50.24^2/4pi
A=200.85 sq. cm
