Question

The circumference of a circle is 44m.what is its area?

Answer 1

Given, 2πr=44( Circumference)
=>r=22/π=7 m
Now, area of the circle = >πr^2 =π × 7 ×7= 154 sq. m

Answer 2

$2 \times \pi \times r$
it is the circumference of the circle.
By this, radius= 7 m .

$\pi \times r ^{2} = area$
by this the area is equal to 22 m
