Lesson Summary:

In this lesson, you will learn how to find the area of a circle given its diameter. The diameter is the distance across the circle, while the radius is the distance from the center to the outside. The area of a circle is pi times the radius squared. By finding the radius, which is half of the diameter, you can easily calculate the area of the circle using this formula. Leave the answer in terms of pi for an exact answer.

Find the area of a circle given the diameter

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
