Question

Find the area of a circle with a circumference of 6.28 units.
units²

Answer 1

2.54 units²

Explanation:

To find the area first find the radius from 2πr since the cricumference, C was given

C = 2πr

6.28 = 2 x 22/7 x r

6.28 = 44r/7

r = (7 x 6.28)/44

r = 0.9

So now the area = πr^2

22/7 x 0.9^2

=2.54 units²
