SOLUTION: Two concentric circles( bigger and smaller) have radius R and r respectively. Determine the cross section area thus formed when an 8cm line drawn is tangent to the smaller circle

Question 1143640: Two concentric circles( bigger and smaller) have radius R and r respectively.
Determine the cross section area thus formed when an 8cm line drawn is tangent to the smaller circle and serve as chord to the smaller circle and serve as to the bigger circle.

A cross sectional area is an area of a 2-dimensional figure that is formed by passing a plane through a 3-dimensional figure.

Your post describes a 2-dimensional figure; there is no cross section. If you want help with your question, post it so it makes sense.
