For Programming Assignment $1,$ you are required to write Python scripts $($or programs$)$ that compute the following. $[$MO $1\mathrm{.}2]$

$($a$)$ Write a script to compute and print the surface area of a sphere with radius $10.$ The surface area is given by $4\backslash$pi r$^2$ where r is the radius and $\backslash$pi is $3\mathrm{.}14.$ Your script should include in$-$code comments as necessary to allow a reviewer of the program to understand the objective and functioning of it$.$ Comments in Python begin with the # character.

$($b$)$ Write a script for computing and printing the speeding fine of a motorist. Assume the speed limit is $65$ mph$,$ the motorist was traveling at $85$ mph and the ticket is $$5$ for each mph over the speed limit$.$ Your script should include in$-$code comments as necessary to allow a reviewer of the program to understand the objective and functioning of it$.$ Comments in Python begin with the # character.

Submit your programs as script files named $$COS$-101\_$PA$1$a$\_.$py$$ and $$COS$-101\_$PA$1$b$\_.$py$,$ respectively.
