I can identify and describe the properties of circles, including radius, diameter, circumference, and area.
- 1
The formula for finding the circumference of a circle is Circumference = Pi × diameter, or C = πd.
- 2
The formula for finding the area of a circle is Area = Pi × radius squared, or A = πr².
- 3
To find the radius when you are given the diameter, you divide the diameter by 2.
