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.

You did not describe the diagram.
What region is shaded?
how big is the circle, what is its radius ?

anyway:
subtract the area of the circle from the area of the rectangle.
Answered by Anne
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?
Answered by Reiny
only if the circle touched both sides of the rectangle. Then the diameter of the circle would be the width of the rectangle.
Take half the diameter to get the radius
