Question

The area of a circle is154cmsq find its circumference

Answer 1

⛧Hello....

⛧HERE IS THE ANSWER


⛧Area of a circle = πr2

so, 154 = 22/7 x r2

r2 = ​154 x 7/22 

r2 = 49

r  = 7

⛧As we know Circumfrence of a circle = 2​πr

= 2 x 22/7 x 7

= 44 

⛧Hence circumfrence of circle = 44 cm
 

⛧Hope it helps to you.
