Circle Intro and Arc Length

I introduce many basic definitions that are related to circles and also the area and circumference formula. I then work through many examples examples of naming minor and major arcs, central angle, and finding arc lengths.

Welcome...I'm glad I "popped up" and was able to teach you what you needed:) Thanks for supporting by subscribing! Please be sure to share with your friends:D
If you are bored over the summer, I even made a calligraphy video teaching basic capital cursive that you could learn yourself!

Professor RobBob, thank you for a smooth Introduction on Finding Area and Arc Length of a Circle. These are well known formulas that can also be used to find the area of a sector of a circle. I took a course in Survey Computations and these formulas were constantly used throughout the class.

Thanks...I learned calligraphy in high school and found it to make the problems easier to read for the students so it has just been a talent that stuck with me through the years...thats even part of the reason I met my amazing wife of almost 20 years<3
Thanks foe choosing my video to learn from and I hope you will return for more!

It helps when you love what you do:)...thanks for "liking" my videos!

I don't work with angles measured in radians with my Geometry class. I use your equation for arc length with my trigonometry and PreCalculus students. Thank you for watching. I hope you still found this video helpful.

I am taking geometry this year, and have a not so great math teacher. I missed the day that we went over secants and tangents, so I searched fora video on them. Your's popped up and are amzing! Circles are the most difficult for me, and these make everything so much simpler! Thank you! (subscribed)! Also, as others have mentioned, your handwriting is absolutely gorgeous!

does "arc" and "angle" mean the same thing? according to problem f and g.

I hope you found my video for linear and angular velocity!!!! :D

Nice videos, lol. Very mathy and I see your still in a good mood :D.

can you make a video for central angles please
