WebQ.1: If the radius of a circle is r = 5cm, then find the rate of change of the area of a circle per second with respect to its radius. Solution: Given, Radius of a circle =5cm. We know that, Area of a circle, A = πr 2. Therefore, the rate of change of the area A with respect to its radius r will be: dA/dr = d(πr 2)/dr = 2πr Web`A=pir^2`, where `r` is the radius of the circle or correspondingly: `A=pi/4d^2`, where `d` is the diameter of the circle. If the diameter of the circle `d` and the length of the circumference `C` are known, the area can be calculated (without the figure `pi`) using the formula: `A = Cd/4` Information About the Circle Area Calculator Web18. Think about how the cartesian variables x and y are bounded. If we have the equation. x 2 + y 2 = r 2 ⇒ x = ± r 2 − y 2 or y = ± r 2 − x 2. And x , y < r.
