How do I find the area of a circle's shaded region?

vlabodo [156]

Answer: There are two ways you can do this; by radians or by degrees.

Step-by-step explanation: The formula used for calculating an area of a circle's shaded region in RADIANS is: A = (θ / 2) × r^2 and θ is equivalent to radians. The second formula used for calculating an area of a circle's shaded region in DEGREES is: (θ / 360) × πr2 where θ is equivalent to degrees.
