I have to design a laboratory activity to answer the question, "What is the relationship between the diameter of a circle and the area of the circle?" My teacher said to use a previous activity as a templete to help me. For the previous activity you had to find the relationship between the circumference and diameter of a circle and to find the circumference you had to use a piece of string and wrap it around the circle.
I need to come up with a procedure to find the area but without using an equation. Any ideas? Please help!!!

bobpursley,
I would put the circle on grid paper, and then determine the area by counting squares.
