I assume A is the area between the 2-cm and the 3-cm circles B is the area between the 3-cm and 4-cm circles. A = pi(3^2 - 2^2) = 5pi B = pi(4^2 - 3^2) = 7pi B/A = 7/5

Make a Venn diagram of two intersectiong circles. Label one PENS and the other PENCILS put 3 in the intersection of both circles leaving 4 to go into the remaining part of circle PENS put 2 in the remaining part of PENCILS adding those numbers: 4+3+2 give us 9 boxes with some ...

No, consider the line joining your two points to be a chord of the circle That chord could be the diameter of the circle or it could be near the edge of the circumference for a very large circle, thus there would be an infinite number of circles possible between these two ...
