For the diameter first of all, would it be 12? Or do I have to subtract?

Thanks.

Would the radius be 6?

Would the area be 354.9456? or 113.04?

**Ms. Sue**, Saturday, September 15, 2007 at 4:39pmYou're right about the radius = 6. And your second answer is correct for the area.

The area is PI * r^2.

3.14 * 36 = 113.04.
