I’m failing geometry:(

 

Hello guest!

 

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

\(r=1.414cm\)

laugh  !

I do not think that is correct asinus.  sad

 

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

I do not know intersecting cord theorum.

I was just going to use distance XB=distance XE and solve the equation for k

X(1,k)  k is the radius.
