Each side of a square is 44 cm. Find its perimeter. If this perimeter is equal to the circumference of a circle, find the radius of the circle.

Solution

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
