Answer:

Given area of the circle = 308cm²

Radius of the circle = ?

We know that area of circle is πr². So, by substituting the values, we will get the radius value.

⇒ Area of the circle = πr²

⇒ 308cm² = 22/7 x r²

⇒ 308 x 7 / 22 = r²

⇒ 98 = r²

\sqrt[2]{98} = r

⇒ 9.8cm = r

Now that we have found out the radius, we can now find out the circumference of the circle.

⇒ 2πr

⇒ 2 x 22/7 x 9.8

⇒ 61.6cm

∴ Hence, the circumference of the circle is 61.6cm

Thnx and have a nice day!
