Answer:
Concentric circles are circles with a common center. The region between two concentric circles of different radii is called an annulus. Any two circles can be made concentric by inversion by picking the inversion center as one of the limiting points.
1. Picking any two points on the outer circle and connecting them gives 1/3.
2. Picking any random point on a diagonal and then picking the chord that perpendicularly bisects it gives 1/2.
3. Picking any point on the large circle, drawing a line to the center, and then drawing the perpendicularly bisected chord gives 1/4.
So some care is obviously needed in specifying what is meant by "random" in this problem.
Given an arbitrary chord BB^' to the larger of two concentric circles centered on O, the distance between inner and outer intersections is equal on both sides (AB=A^'B^'). To prove this, take the perpendicular to BB^' passing through O and crossing at P. By symmetry, it must be true that PA and PA^' are equal. Similarly, PB and PB^' must be equal. Therefore, PB-PA=AB equals PB^'-PA^'=A^'B^'. Incidentally, this is also true for homeoids, but the proof is nontrivial.

If the company sends the contact number in some days, then the request can be sent for the money refund else a complaint can be filed against the company at ftc.gov/complaint.
<u>Explanation:</u>
In today's date, the consumers are the kings and for this there are certain rules and regulations and the protocols which do not let the supplier harm the consumer.
In the case given above in the question, the client should try to get the contact number of the company. If the company sends the contact number in some days then the client can contact the company to get the refund. But in case the client does not get any number to contact the company, then the client should report about the company and the website where the complaint can be filed is ftc.gov/complaint. This website is for the protection of the consumers to put them off the business.
