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:

Let us consider a circle inscribed inside a square

We know that

Side of square = Diameter of circle

AB = 2a

The perimeter of square = 4 × AB

= 4 × 2a

= 8a cm

Therefore, the statement is true.

✦ Try This: What is the perimeter of a square with side 6cm?

We know that

Perimeter of a square = 4 × side

It is given that

Side = 6 cm

So we get

Perimeter of a square = 4 × 6 = 24 cm

Therefore, the perimeter is 24 cm.
