Circumference of a Circle | MathHelp.com

This lesson covers the circumference of a circle. Students learn that the circumference of a circle is the distance around the circle, and the formula for the circumference of a circle is 2 times pi times the radius of the circle. Pi is the ratio of the circumference to the radius, which is approximately 22/7 or 3.14. So a circle with a radius of 3 feet has a circumference of 2 times pi times 3, or 6 pi feet. And since pi = 3.14, 6 pi feet can also be written as 6 times 3.14, or 18.84 feet. Finally, note that the radius of a given circle is half the diameter of the circle. So to find the circumference of a circle with a given diameter, first find the radius of the circle by dividing the diameter by 2.

I have tests coming up, and my teacher didn't even teach us this and told us "learn it on your own" and so i'm here, I understood this in literally a minute and 40 seconds.

Who the hell disliked this? Teachers that took 3 days to explain this?

I feel bad for the people who had to look it up and realize that their teacher couldn’t teach em as best as this.

Tysm! Your lessons are so much better than that of my teacher- I can finally understand circumference of a circle.

[Christian-zost]

You take 2 minutes to make me understand this perfectly but my teacher takes 2 days and I still don't get it. It also helps how nice your handwriting is here. Thank you.
