Calculating Shaded Area.
a = 180-40-30
a =110°
a is angle BAC.
(6/sin40) = (b/sin30)
b = 4.66717148058 cm.
b is AB.
c = a-90
c = 20°
cos20 = (0.5*4.66717148058)/d
d = 2.48335007498 cm.
d is the radius of the circle.
e = 180-2c
e = 140°
Therefore Shaded Area is;
(140π*2.48335007498²/360)-(0.5*2.48335007498²sin140)
= 7.53444556147-1.9820444633
= 5.55240109817 cm²
