Write the equation of a circle given the center and a point it passes through

Learn how to write the equation of a circle. A circle is a closed shape such that all points are equidistance (equal distance) from a fixed point. The fixed point is called the center of the circle while the distance between any point of the circle and the center of the circle is called the radius of the circle.

To write the equation of a circle, we need to know the length of the radius of the circle and the coordinate point of the center of the circle. Given a circle whose center is at (h, k) and the length of the radius is r, the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2.

Thank you for actually teaching me. Currently, all my teacher does is powerpoints, this is actually teaching me.

You know it is really convenient when I just search up any problem I have in math and your videos come up. You have seriously helped me out so much. I am currently prepping for SATs and I will be on your channel for a while haha

Real helpful during this quarantine when my teacher doesn’t include it in the video and I xpects is to know it

If I werent for your videos I would be failing math. My school decided that students are better off teaching themselves how to do math.🤦‍♂️ so thank you, much love.

thank you so much for making these videos, I’ve watched so many of these to help with my ap calc summer homework 💀💀😂 I just wanted to tell you thanks just in case you were feeling unmotivated to do these anymore and tell you that many students are grateful for this so PLEASE DO NOT STOP 🙏🏽

My math teacher discusses for 2 hours and yet u just discussed for minutes and i had learned more lol
😂

Omg I wish I had you as my teacher, this makes so much sense. We had a whole class for this one equation and I didn't understand it until this 3 minute video, thanks!

[MarsPotatoes]

I wish I had you as my teacher. I’m absolutely lost in my math class and your videos are a lifesaver

[itsschychyv]

im watching this video now because i can’t understand the way my teacher explains it and we’re doing online school and all i can say is your videos are so helpful to me i understand everything clearly

[IvoryOut]

Once again you have saved me hours of ripping out my hair. Thank you Brian. Do you have any formula sheets available?

[xtraodnary]

i must say you're a great teacher because when I watched a lesson on your channel to advance in class because i was out and the next morning we had a quiz. I simply perfected it so thanks a lot

[heymonth.]

Thanks sir
Respect from India🇮🇳🇮🇳🇮🇳🇮🇳

[mosoulwrites]

Sir thank you so much. You ate this lesson. Thank you for your service. 🧡

[kanekikeng]

Thank god for this man and his videos, my teacher doesn’t help as much

[andrewkasonde]

Excellent have understood 99.9% of it you're a good lecturer 💯💯💯👏

[thomaslee]

This guy is seriously a legend. My math professors are too lazy to walk the class through these examples, so I go to youtube and search Brian McLogan (any topic imaginable) and I can always count on a clear explanation. Thanks

[cristina]

so helpful!! i know this is an old video but thank you for uploading your work in classes. i have a bad professor rn so this is so helpful to me TYSM😁

You can just find the distance between the 2 points using D=√(x2-x1)²+(y2-y1)²

Up at 5 am. Should have just looked this up earlier! Almost done with my Homework!! Thank you!
