Polar moment of inertia of circle: Derivation, Formula, Examples

WebThis video gives an informal explanation as to why the derivative of the area of a circle is equal to the circumference. WebFirst you need to know that the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 where the center is at point (a,b) and the radius is r. so for instance (x-2)^2 + (y-3)^2 = 4 would have the center at (2,3) and have a radius of 2 since 4 = 2^2. This means if you went a distance of 2 away from that center point you would be on the circle.
