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. 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.
To find the area of the shaded sector, we need to determine the total area represented by the shaded and non-shaded parts. If the shaded sector is 155 and the rest is 4.3, the total area is 155 + 4.3 = 159.3. The area of the shaded sector is already given as 155, so rounding it to the hundredth gives us 155.00.
To find the area of the shaded sector, we first need to determine the area of the entire circle with a radius of 12, which is calculated using the formula (A = \pi r^2). Thus, the area of the entire circle is (A = \pi (12^2) = 144\pi). If the not shaded area is 100, the area of the shaded sector is then (144\pi - 100). Therefore, the area of the shaded sector is approximately (144\pi - 100) 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.
To find the area of a shaded sector, you typically need the radius and the angle of the sector in degrees or radians. However, your question provides two numbers, 12 and 100, without context. Assuming 12 is the radius and 100 is the angle in degrees, the area of the sector can be calculated using the formula ( \text{Area} = \frac{\theta}{360} \times \pi r^2 ). Plugging in the values, the area would be approximately 25.13 square units.
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.
