How to Calculate Area Of Segment Of Circle
Example: What is the area of segment of circle with radius = 8 units and angle = 118 units?
As;
area of segment of circle = (angle*π/360-sin(angle)/2)*(radius)2
By substituting the above given data in the previous function;
(i.e.) = (118*π/360-sin(118)/2)*(8)2
Answer is: units2.
