Description
html markup
shown to student

You are invited to a math party. Because no math party is complete without pie, your classmates decided to bring various pies with different radii and slice them at differing increments.
Before anyone is allowed to eat the pie, they must calculate the area of the top of the pie slice they have received, given the radius and the angle (in degrees). 

Write a program able to calculate the area of your pie so you can eat quickly!
Use the degrees to determine the fraction of the pie you receive, and use the radius to determine the total size of the pie!
