Question

the area of a circle is 616 square cm. Find the circumference of circle
​

Answer 1

⭐⭐ Hey mate ⭐⭐

Here's the answer :-

Guven,

Area of circle = 616 cm²

As we know that ,

area of circle = πr²

and to find the circumference , we will need radius .

Here ,

according to the question :-

area = πr²

616 = 22/7 × r²

616 × 7/22 = r²

196 = r²

r = √(196)

r = 14 cm

Circumference = 2πr

=> 2 × 22/7 × 14

=> 44 × 2

=> 88 cm

$\boxed {circumference\;=\;88cm}$

Hope it will be helpful.

Answer 2

Area of circle = πr² = 616 cm²

616 × 7/22 = r²

196 = r²

r = √(196) = 14 cm

Circumference = 2πr = 2 × 22/7 × 14 = 44 × 2 = 88 cm
