Thanks for the reply.

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

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.

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

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

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

Have tried in vain to find the radius.
