Question

calculate the area of segment of a circle of radius 5 cm if the degree measure of the arc of the segment is 80° and the length of the chord is 8cm
​

Answer 1

Area of Sector = θ × π 360 × r2 (when θ is in degrees)

Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)

L = θ × π180 × r (when θ is in degrees)
