The circumference of circle x in which a = 49pi in squared

C = 14 pi inches

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

49 pi = pi r^2

Divide each side by pi

49 pi/pi = pi / pi r^2

49 = r^2

Take the square root of each side

7 = r

The circumference is given by

C = 2 * pi * r

C = 2 * pi * 7

C = 14 pi inches
