Answer:
Given,
Area of square= 196 cm^2
We know, Area of square= (Side)^2
Therefore x^2=196
X=14cm
Given,
Diameter = Side of the square
Therefore, radius = 1/2 side
= 1/2 *14
= 7 cm
Circumference= 2 pi * radius
= 2 x 22/7 x 7
= 2 x 22
= 44 cm
Area of circle = pi * (radius)^2
= 22/7 x 7 x 7
= 22 x 7
= 154 cm^2
