Exploring Circle Properties

8th Grade•60 minutes

Learning Objective

I can identify and describe the properties of circles, including radius, diameter, circumference, and area.

The formula for finding the circumference of a circle is Circumference = Pi × diameter, or C = πd.

The formula for finding the area of a circle is Area = Pi × radius squared, or A = πr².

To find the radius when you are given the diameter, you divide the diameter by 2.

This lesson includes 12 practice questions to reinforce learning.
