Derivation of circumference of circle
WebSometimes, the radius of the circle may not be directly available to you. So, here are the formulas for the area of a circle using the diameter or circumference. 1. Using Diameter (d) Here’s how we get the formula. First, we find the radius in terms of the diameter. And then, we substitute this value of r in our standard formula.
