WebFeb 1, 2024 · The circumference or perimeter of a circle is defined as its boundary or complete arc length. In a circle, all the points lying on the boundary are equidistant and are placed at equal distances from the center. The formula to calculate the circumference is given by the product of π (which is a constant value) and the diameter of the circle. Web(a) Use the formula for the area of a circle of radius r, A = πr 2, to find dA∕dr. (b) The result from part (a) should look familiar. What does dA∕dr represent geometrically? (c) Use the difference quotient to explain the observation you made in part (b).
