perimeter of square = 4a = 4 * 11 = 44cm
C = 2 * pi * r = 44cm
44 = 2 * 22/7 * r
r = 44 * 7 / 22 *2
r = 7cm
Area = pi * r * r
A =22/7 * 7 * 7
A = 154 cm²
C = 2 * pi * r = 44cm
44 = 2 * 22/7 * r
r = 44 * 7 / 22 *2
r = 7cm
Area = pi * r * r
A =22/7 * 7 * 7
A = 154 cm²

given,
side of square ,a=11cm
circumference of circle=perimeter of square
2πr=4a
2πr=4×11
2×22/7×r=44
r=44×7/44
r=7
area of circle=πr^2
=22/7×7^2
=22/7×7×7
=154
