1-73.

Consider circles of different sizes. Create multiple representations of the function ( table, equation, and graph) with inputs that are the radius of the circle and outputs that are its area.

How do you find the area of a circle? (If you forgot, try searching for the formula on the Internet.)

Which variable is independent, the radius or the area?
