Question

Area of a square inscribed in a circle with radius r 8cm

Answer 1

Here is your answer

When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle. 

So Side of a square is = 2x Radius. = 2x8

=16 cm

Area of square = side x Side

= 16 x 16

=256 sq cm Answer

Hope it helps you

Answer 2

Hey there!

Given,

Radius of circle = 8 cm

Diameter = 2 * r = 16 cm

Here, The diameter of circle = diagonal of square = 16 cm

Then, Area of square = diagonal^2/2

                                  = 16^2/2

                                  = 256/2

                                  = 128 cm²

Good day!
