**Geometry**

Sorry it wasn't complete. The shaded area is the area outside the circle. No radius was given for the circle. Does that mean that I can get the radius of the circle from the rectangle's dimension?
*July 14, 2016*

**Geometry**

Find the area of the shaded region, if the rectangle has dimensions 8m and 18m and the circle is inscribed in the rectangle. I just need an example on how to solve for this. I'm pretty bad at following without examples and my book doesn't show one.
