The area of a circle is found with the formula A= 3.14r2 where 3.14 represents 3.14. If a tile artist is placing tiles in a circular mosaic pattern and the area of the circle is 658 square feet what is the approximate radius of the circle in feet?

  1. 658 = 3.14 * r^2

    658 / 3.14 = r^2

    209.55 = r^2

    14.5 = r
