ruck'n'reefer is on a distinguished road

need help from a math wiz!!!

I need to find the area of...part of a circle.
It has a 2.5 inch diameter. I need to know the area of the 1/2 inch outer cross section.
I hope this makes sense.
If I was to cut off 1/2 an inch of the circle how much would I have?

Thanx muchly
