Answer 2

Answer:

The circumference of a circle can be easily found from the area of the circle. From the area of the circle, 'A', we can compute the radius of the circle, 'r', and then from the radius, the circumference of the circle can be calculated. A = πr2, r=√Aπ r = A π , and C = 2πr = 2π√Aπ π A π .
