How to calculate the area of a circle

I go through two examples, one given the radius, and another given the diameter

[@Cocoagoddess_]

I'm embarrassed to say this but I'm 29 and will soon be receiving my high school diploma this year. When I was in high school I had to take geometry and I never understood it. No matter how much tutoring I received, how the teacher taught it I just never understood it. I skipped over the geometry course of my high school diploma program for months until lastnite. I faced my fears by clicking on it only to find out all I had to do was 3 assignments on finding the areas and perimeters for rectangles, triangles and circles. Low and behold I watched the required videos knowing I would be confused......to my surprise I understood it!!!! And once I had to take the final exam I got each and every problem correct. Kinda didn't understand the video for finding the area for circles so I came to your video and after just 3 minutes, I get it. Thank you so much for posting this very helpful video. I hated math all my life but now that I understand this portion of geometry I'm in love with it

If you couldn't understand this lesson in 30 minutes, you should see a doctor.

@Ameen Djoudi r stand for Radius, the radius is that half line you see in the circle that goes from the center to the outline :) if you wanna find out more about that look up a circles diameter, radius, and circumference

My teacher talked about this for an hour. Learned nothing from that 1 hour WAISTED.
Watched this 3 minute video and learned everything I need!
I do not know how you do it but this is super clear and easy.

This is by far the best video and examples given for understanding how to formulate the calculation - thank you very much. Simple and clear.
All other examples assume one understands the principle, and fail to explain this, thereby causing confusion using complicated formulae and jargon.

I know I’m a few years late but if your teachers are picky😂 after your area answer add square which is the tiny two and how much the radius or diameter is like m or mm or cm. Hope that helped? No hate awesome job

If circle is 30 mm
and I want to increase for 0.25mm
Should I 0.25/2 = 0.125
And then 0.125 + 30 mm =30.125 mm
or should I 30mm + 0.25 = 30.25 mm
What is now correct?
