A circle of radius 8 cm circumscribed a square. The length of the side of the square is:

Correct option is C

Given:

Radius o Circle = 8 cm

Solution:

Diameter of the circle = 2 × 8 = 16 cm.

Diagonal of the square = √2 a

As we know

If square inscribed in a circle, then

Diagonal of the square = Diameter of the circle

√2 a = 16

 a = 16/√2

 a = 8 √2
