What A circle with a radius of 3 cm shares a center with another circle that has a radius of 5 cm. Find the probability that a randomly selected point is in the larger circle but not in the smaller ci?

We can look at total areas (and ignore units-they're all the same). The smaller circle has an area of 9pi, and the larger circle has an area of 25pi. The smaller circle is entirely inside of the larger circle. So anything not in the smaller circle is in the larger circle. 16pi square centimeters are part of only the larger circle. 16pi/25pi=.64. So the desired probability is .64.

What is the cross section of a circle?

The cross section of a circle is a circle. A circle is defined as a plane figure (i.e. 2 dimensional object) with a constant radius in both dimensions. Since a cross section is, by definition 2 dimensional, a circle's cross section is the circle itself.
