Derivative of area of a circle
WebMar 24, 2024 · This derivation was first recorded by Archimedes in Measurement of a Circle (ca. 225 BC). If the circle is instead cut into wedges, as the number of wedges increases to infinity, a rectangle results, so (5) From calculus, the area follows immediately from the formula (6) again using polar coordinates . WebArea of Circle = πr2 or πd2/4, square units. where π = 22/7 or 3.14. The area of the circle formula is useful for measuring the space occupied by a circular field or a plot. Suppose …
