Question

circumference of circle is 44 then its area is ​

Answer 1

Since we know that,

Circumference =

$2\pi \: r$

Therefore,

44= 2 (pi) r

r=22/pi

Now, Area =

$\pi \: r {}^{2}$

Therefore Area = (pi) (22/pi)^2

= 154 unit^2

Answer 2

Circumference = 2pi r

44 =2 ×3.14x r

44 = 6.28 x r

44/6.28= r

r= 7cm

Area of circle= pi r square

=3.14 x 7x7

= 153.86 cm sq.
