Question

The area of a circle is 616cm2 , calculate its circumference

Answer 1

Hey !!!

Area of cirlcle = 616cm²

Area of cirlcle = πr²

•°• 616 = πr²

616 × 7/22 = r²

28 × 7 = r²

196 = r²

r = 14

Circumference of cirlcle = 2πr

2×22/7×14

=> 88cm Answer !!!

Answer 2

Area of circle = 616cm²
Area of circle = πr^2

616 =πr^2
616 ×7/22 = r2
28 ×7 =r^2
196=r^2

r=14

Circumference of circle = 2πr

=2x22/7*14
=2×22×2
=88cm
