Oh, dude, finding the area of a shaded sector is like finding the square footage of a slice of Pizza. You take the central angle of the sector, divide it by 360 (the total degrees in a circle), then multiply that by the area of the full circle. It's like calculating how much of the pizza you're getting - just with math instead of a slice of pepperoni.
find the area of the shaded sector 12cm and 24°
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
(pi * radius squared) * ( sector angle / 360 )
0. There is no circle so no shaded area of a circle!

find the area of the shaded sector 12cm and 24°
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
The area of the shaded sector is: 245.7 square units.
72pi
(pi * radius squared) * ( sector angle / 360 )
0. There is no circle so no shaded area of a circle!
area of whole circle = pi * radius squared = 3.14159 * 36 = 113.1area of sector = 113.1 * ( 10 / 360 ) = 3.14159 sq units
35.35 sq un
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.
