The area is r^2*x where r is the radius of the circle and x is the angle measured in radians.
If you are still working in degrees then Area = (y/180)*r^2, where the angle is y.

Find the area of the shaded sector. radius of 3 ...A+ = 7.07
(pi * radius squared) * ( sector angle / 360 )
find the area of the shaded sector 12cm and 24°
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
