Will it be true to say that the perimeter of a square circumscribing a circle of radius a cm is 8a cm? Give reasons for your answer.
Solution
The perimeter of a square = 4 side
The radius of the circle = a
Diameter of circle =2 radius= 2a
Side of square =diameter of circle= 2a
Perimeter of square =4 side=4 2a=8a
The perimeter of a square is 8a
Hence, the given statement is true.
