Question

Area
circle is 154 cm², find
its circumference.​

Answer 1

Answer:    44 cm

Step-by-step explanation:

Area of a circle = $\pi$$R^{2}$

               154 = $\pi R^{2}$

              154/22 * 7 = R^2

              R = 7

circumference = 2$\pi$R

                        = 2 * 22/7  *7

                        = 44 cm

Hope this helps
