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 … WebA = PI r^2 A = PI (C/2PI)^2 <- put the formula for radius into the formula for area. A = PI (C^2/2^2 PI^2) <- note that both 2 and PI are squared in this step A = PI (C^2/4PI^2) A = PI (C^2)/4PI^2 A = C^2/4PI <- at this step it seems like some kind of magic happened to get rid of the squared PI in the denominator but think of it like this:
