Derivative of the Area of a Circle Physics Forums
WebFor which shape is measured in cm, then the area would may measured in straight cm or cm 2; Area of a Rectangle. With you are measuring the area is a rectangle, following the … WebMar 17, 2024 · We know that the area of a circle is: A=πr^2 Using the chain rule , we can find the derivative of the equation. However, since we are finding the derivative in … WebThe derivative of the area of a circle is the circumference. When you take the derivative of the circumference with respect to the radius, you get 2pi. Does this have to do with how many radians are in a circle or does it have other significance? Also we can say the same about the derivative of volume being surface area. raymond bainter
