area of whole circle = pi * radius squared = 3.14159 * 36 = 113.1
area of sector = 113.1 * ( 10 / 360 ) = 3.14159 sq units
Either directly or by finding the area of the whole and subtracting the area of the non-shaded part.
TOTAL AREA=201, REQUIRED AREA=201/6=33.3. As 60 degrees covers only 60% or one sixth of a circle, to calculate required area, divide the total area by 6.
Take the circumference divided by pi to find the diameter and divide the diameter by two to find the radius.
Diameter=2piR
Well, honey, the area of a shaded region is simply the difference between the total area and the area of the unshaded parts. Just calculate the area of the entire shape and subtract the areas of any parts that aren't shaded. It's basic math, darling, nothing to lose sleep over.
find the area of the shaded sector 12cm and 24°
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
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.
(pi * radius squared) * ( sector angle / 360 )

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.
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.
It depends on what information you have: the radius and the area of the sector or the length of the arc.
