Answer:
Given: Area = 27 unit²
⇒ πr² = 27 unit²
⇒ r² = 27/ π
⇒ r² = 3.68 (approx and by using calculator)
⇒ r = √3.68
∴ r = 1.92 (approx)
now,
cirumferene of circle = 2πr
= 2 × 22/7 × 1.92 unit
= 84.48 / 7 unit
= 12.07 unit (approx)
∴ So the circumference of circle is 12.07 unit.
hope u it will help u.
