WebOct 25, 2024 · Suppose a circle has a radius 'r' then the area of circle = πr2 or πd2/4 in square units, where π = 22/7 or 3.14, and d is the diameter. Area of a circle, A = πr2 square units. Circumference / Perimeter = 2πr units. Area of a circle can be calculated by using the formulas: Area = π × r2, where 'r' is the radius. WebFeb 9, 2013 · If you increase the radius of a circle by a tiny amount, dR, then the area increases by (2πR) (dR). The same “derivative thing” holds up for the circumference vs. the area of a circle. The change in area, dA, is dA = (2πR)dR. So, . That is, the derivative of the area is just the circumference.
