I’m failing geometry:(

Hello guest!

$$r^2=(\frac{a}{2})^2+(\frac{a}{2})^2\\ r^2=(\frac{2cm}{2})^2+(\frac{2cm}{2})^2\\ r^2=2\cdot 1cm^2\\ r=\sqrt{2cm^2}$$

$$r=1.414cm$$

I do not think that is correct asinus.

My image is below.

I was going to give you teaching instruction but CPhill is answering so I am sure he will give you the whole lot.

I hope you have the sense to learn from it.

We can use the intersecting chord theorem here

Let 1/2 the side of the square  = 1

Let  the  diameter of the  circle be  2  +  x

We have that

1 * 1   =   2 * x

1  = 2 *  x

x =1/2

The diameter  =    2 + 1/2  =   5/2

The radius is 1/2 of this =   5/4
