$1(50$ points$).$ Write a Python program that reads one circle and one point, then determines

whether the point is inside the circle, on the border, or outside. Note that a circle will be

represented by its center $(cx,cy)$ and radius $r$ while the point is represented by $(x,y).$

$2(50$ points$).$ Suppose the cost of airmail letters is $30$ cents for the first ounce and $25$ cents for

each additional ounce. Write a complete Python program to compute the cost of a letter for a

given weight of the letter in ounce. Some sample runs:

input output

$0\mathrm{.}530$ cents

$130$ cents

$1\mathrm{.}155$ cents

$255$ cents

$2\mathrm{.}580$ cents
