Question

A wire bent in the form of a circle of radius 42 cm is again bent in the form of a square. What is the ratio of the regions enclosed by the circle and the square? *

Answer 1

Answer:

Ratio is 1:1

Step-by-step explanation:

Radius of Circle = 42 cm (given )

Area of circle= πr²

Area of circle = 22/7×42 = 132 cm²

As the shape of the wire changes but the area remains the same. So area of Square is equal to the area of Circle .

Area of Circle= 132 cm²

Area of Square= 132 cm²

Ratio = 132 cm²/132 cm²= 1:1
