Find the area of the shaded part in the figure. Use 3.14 for pi and round your answer to one decimal place.

The figure is a circle inside of a square. The square measures 15' x 15' with the circle touching all four sides.

Re: Finding the area

Subtract the area of the circle from the area of the square. The diameter of the circle must be 15'.

The areas that are shaded are the triangles at each corner of the rectangle where the lines of the circle do not touch.
