Area_circle = π × radius²
Area_sector = fraction of area_circle
fraction_of_circle = angle_at_centre/full_turn
→ area_sector = 120°/360° × π × (8 cm)²
→ area_sector = 64/3 × π cm²
→ area_sector ≈ 67.02 cm² (≈ 67 cm²)

Calculate a sector of a circle if the angle is 150 degrees and the radius is 13cm?
The area of the sector is: 221.2 cm2
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 90 degrees?
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
A sector of a circle has a central angle of 50 and an area of 605 cm2 Find the radius of the circle?
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 60 degrees?
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.
How do you find the area of shaded sector of a circle?
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.

A central angle measuring 120 degrees intercepts an arc in a circle whose radius is 6. What is the area of the sector of the circle formed by this central angle?
The area of the sector of the circle formed by the central angle is: 37.7 square units.
What is the radius of the sector with an angle of 27 degrees and arc of 12cm?
The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm
A sector of a circle has a central angle of 50 and an area of 605 cm2 Find the radius of the circle?
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
What is the area of a sector whose central angle is ninety degrees and has a radius of ten inches?
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
How do you find the area of a sector of a circle when you're given only the radius and not the degrees?
You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.
Area of a part of circle?
Area of a sector of a circle = (pi) x (radius)2 x (central angle of the sector / 360)
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 60 degrees?
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.
What is the area of a circle if the area of its sector is 49?
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
What is the area of the shaded sector if the circle has a radius of 8 and the central angle is 100 degrees?
Assuming the shaded sector has the angle of 100o (without seeing the diagram, it could be the other sector, ie the one with an angle of 260o): The sector is 1000 ÷ 360o = 5/18 of the circle. Thus its area is 5/18 that of the circle: area = 5/18 x π x 82 ~= 55.9 units2
