The area of a circle is found with the formula a = the expression is pi times r squared., where pi represents 3.14. if a tile artist is laying down tiles in a circular mosaic pattern and the area of the circle is 706.5 square feet, what is the radius of the circle in feet?

Okay. The formula for the area of the circle is A = πr². To find the radius, we would first do the steps in reverse. Let's divide the area by pi (3.14) 706.5/3.14 is 225. With that, the square root of 225 is 15, because 15² is 225. There. The radius of the circle is 15 feet.
