Question

what is area of circle formula ?​

Answer 1

Area of Circle

Area of a circle is the region occupied by the circle in a two-dimensional plane. It 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 unit) where π = 22/7 or 3.14

Answer 2

Answer:

$Area = π x r2,$

Area of circle can be calculated by using the formulas: Area = π x r2, in terms of radius 'r'. Area = (π/4) x d2, in terms of diameter, 'd'. Area = C2/4π, in terms of circumference, 'C'.

In geometry, the area enclosed by a circle of radius r is πr². Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter, approximately equal to 3.1416
