Question

Find the areaof circle whose circumference is 22​

Answer 1

Answer:

let the radius be r

circumference =2πr=22

r=22/2π

r=22x7/22x2

r=7/2

area=πr^2

22/7x7/2x7/2=77/2

=38.5

ans - 38.5unit^2

Answer 2

Answer:

38.5 units.

Step-by-step explanation:

GIVEN , 2πr =22

=> πr=11

=> r = 11×7/22

=> r = 3.5

NOW, area = πr^2

=> 22/7×(3.5×3.5)

=> 22×0.5×3.5

=> 11×3.5

=> 38.5

THEREFORE, area of circle is 38.5 units.
