theta (angle)
_____ X pi r squared
360
Note that if the angle is measured in radians, then you only need to do Θ*r².
A full circle is 360° or 2*pi radians
160 20ft
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!
35.35 sq un
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
Find the area of the shaded region means find the area of the area that is shaded in or darkened.
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.
