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.
