We are in the middle of our circle unit. We now know that there is a relationship between the diameter of a circle and the circumference of the same circle. We learned that no matter what the size of the circle the circumference will always be a little more than 3 of the diameters. We use 3.14 or pi to represent how many diameters we use.
The formula is C = pi × diameter
Now that we know circumference we will move on to area of a circle.
