Question

the area of circle is 616 m square find its circumference

Answer 1

Hey dear here is your answer!!!!!

___________________________

We have been given that the area of a circle is 616 m².

We also know that the area of a circle is πr².

So, according to question:-

πr² = 616

$\frac{22}{7}$  x r²= 616

Transposing:-

r² = $\frac{616X7}{22}$

r² = 196

r = √196

r = 14 m.

Now, we also know that the circumference of a circle is 2πr.

= 2 x $\frac{22}{7}$ x 14

= 2 x 22 x 2

= 88m

So, 88m is your answer !

❣️⭐ Hope it helps you dear...⭐⭐❣️❣️

Answer 2

$\huge\mathcal{Answer \ :-}$

$\mathsf{Given \ :-}$

Area of circle = 616 m²

Also,

Area of circle = πr²

•°•

πr² = 616

22/7 × r² = 616

r² = 196

r = 14 m

Now,

Circumference of circle = 2πr

= 2 × 22/7 × 14

= 88 m.
