Hello,

to #37:

Plug in the given values:

Plug in the given values and solve the equation for t:

to #38:

If

- r is the radius of the smaller circle,

- R is the radius of the larger circle,

- d is the diagonal of the smaller square,

- D is the diagonal of the larger square,

- s is the side of the smaller square and

- S is the side of the larger square

then you have:

therefore s = 6

Therefore R = 12 - December 14th 2007, 05:27 AMSoroban
Hello, Raleigh!

38. A square fits just inside a circle whole radius is

There is second square that fits around that circle

and a second circle around the second square.

What is the radius of the second circle?

Code:`* - - * - * - * - - * B`

The radius of the first circle is: .

The radius of the second circle is: .

We have a 45° right triangle.
