Find the circumference of a circle whose area is 154 $$m^2.$$​​

Correct option is A

Given:
Area of circle = 154 $$m^2$$​​
Formula Used:
Area of circle = $$\pi r^2$$​​
Circumference of circle = $$2\pi r$$​​
Solution:
Area of circle = $$\pi r^2$$​​
​$$154 = \pi r^2\\154 = \frac{22}{7}\times r^2\\r=\ \sqrt{\frac{154\times7}{22}}\\r = 7 cm\\$$​​
Circumference of the circle = $$2\times\frac{22}{7}\times7$$​ = 44 cm
