Question

If area of a circle is 49/64 pie cm square,then find the circumference of the circle?​

Answer 1

7/4 * pi

Explanation:

Area of circle = pi * r^2

Find radius:

pi * 49/64 = pi * r^2

49/64 = r^2

7/8= r

Circumference of circle = 2pi * r

2 * pi * (7/8) = 7/4 * pi

Assuming that the answer is in terms of pi as the question is in terms of pi
