उत्तर
The side of a square = 44 cm
∴ Its perimeter = 4 × Side
= 4 × 44 = 176 cm
Since, Its is given that, Circumference of a circle = Perimeter of a square
∴ Circumference of a circle = 176 cm
Let, the radius of the circle = r
⇒ 2πr = 176 cm
r = `(176xx7)/(2xx22)` = 28 cm
∴ The radius of the circle = 28 cm
