A piece in the form of rectangle measures 52cm *36cm .It is cut in one place and bent in the shape of a circle.Find the radius of the circle.

Given, dimensions of rectangle are 52 cm × 36 cm.

So, perimeter of rectangle = 2(l + b) = 2 (52 + 36) = 2 × 88 = 176 cm

Now the given rectangular piece is bent in the form of a circle.

Therefore, circumference of circle = 2πr
