An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
It is found by: (sector area/entire circle area) times 360 in degrees

Area of a sector of a circle.
Sectors don't have diameter, only radius. However... Assuming the the circle has a diameter of 9.9 then the area of the circle is 4.95 x 4.95 x 3.14 which is 76.93785 cm2. As the sector has a central angle of 130o then its area is 130/360 of the above figure ie 27.28 cm2 to two decimal places.
To find the area of sector CED, we need the radius and the angle of the sector. If DE is the radius (15 yards), we would also need the angle in degrees or radians to calculate the area using the formula: Area = (θ/360) × πr² for degrees or Area = (1/2)r²θ for radians. Once the angle is provided, we can compute the area accurately. Please provide the angle for a complete calculation.
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
The area of the sector of the circle formed by the central angle is: 37.7 square units.
It is found by: (sector area/entire circle area) times 360 in degrees

Find the area of the shaded sector. radius of 3 ...A+ = 7.07
if given the central angle and the area of the circle, then by proportion: Given angle / sector area = 360 / Entire area, then solve for the sector area
The area of the whole circle is pi*r2 = 25*pi To go any further, you need to assume that the central angle is given in degrees. If the sector is 18.0 degrees out of a circle of 360 degrees so the sector represents 18/360 = 1/20 of the whole circle. The area of the sector, therefore, is 1/20 of the area of the whole circle = 25*pi/20 = 5*pi/4 or 1.25*pi = 12.566 sq inches.
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
A central angle of 120 is 1/3 of the total circle. Aea of a circle = pi x r2, so for this sector the area is (1/3)pi x r2 = (1/3)(3.14)(52) = 26.17
Area of the sector is: (50/360)*pi*6 squared = 5*pi or about 15.708 rounded to 3 decimal places

If the angle at the centre is 60° then the sector occupies 1/6 of the circle as 60/360 = 1/6. The area of a circle = πr² The area of the sector = 1/6.π3² = 9/6.π = 4.712 square units.
