Hint 1: Try forming a right triangle.

Hint 2: Let $O$ be the center of the circle and $X$ be the point where the rectangle touches the circle. Create a right triangle with $OX$ as the hypotenuse and whose side lengths you can easily find.

Thanks, Steven. I tried that before but obviously did not hit upon the correct setup; will go at it again.

You are assuming that rectangle touches the circle, when the illustration shows that it doesn't.

Thanks for the reply.

That's my fault; I didn't draw it correctly. The rectangle is indeed supposed to be touching the circle.

I don't think there is enough info to solve the problem. That's not a circle, it's an oval. It's wider than it is tall. It won't have 1 radius.

The drawing is not correct; I didn't draw it correctly with the Word drawing tool; it is supposed to be a circle.

sqrt [ r^2 - (r-1)^2 ] + r = 5;

r = 6 +/- sqrt(10);

r = 6 - sqrt(10);

r = 2.84
