perimeter of rhombus = 4×s = 4×33 = 132 cm
circumference of circle = perimeter of rhombus
→2πr = 132
→r = 132/2π = 132×7/2×22 = 3×7 = 21 cm
so,
radius of circle = 21 cm
circumference of circle = perimeter of rhombus
→2πr = 132
→r = 132/2π = 132×7/2×22 = 3×7 = 21 cm
so,
radius of circle = 21 cm

How 3×7 comes
dividing 132 by 2 then by 22 will give 3
so 3×7
