Q4 of 78 Page 13

Find the rate of change of the area of a circular disc with respect to its circumference when the radius is 3 cm.

Area of a Circular disc = π r2


Circumference of a Circular disc = 2 π r


Where r = radius of Circular Disc.


Now we need to find where A = Area of Circular disc and C = Circumference of the Circular disk.
