WebIt can be determined easily using a formula, A = πr2, (Pi r-squared) where r is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etc. Area 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. WebSince the unit circle is symmetric with respect to the line y = x, it follows that P lies on the line y = x. So P is the point of intersection (in the first quadrant) of the circle x2 + y2 = 1 and the line y = x. Substituting x for y in the equation of …
