Webπr (squared) gives you the area of a circle, but where does it come from? Here is a simple explanation. The area of a circle is the space occupied by the circle in a two-dimensional... WebThe area of a circle with an angle measuring 360º at the center is given by πr 2, where 'r' is the radius of the circle. If the angle at the center of the circle is 1º, the area of the sector is πr 2 /360º. So, ... On substituting the values in the formula, we get Area of sector (in radians) = [4π/(3×2)] × 12 2 = (2π/3) × 144 = 96π ...
