You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.

To find the radius of the circle, we first need to determine the radius of the sector. The area of a sector is given by the formula A = 0.5 * r^2 * θ, where A is the area, r is the radius, and θ is the central angle in radians. In this case, the central angle is 400 degrees, which is approximately 6.98 radians. Plugging in the values, we get 300 = 0.5 * r^2 * 6.98. Solving for r, we find that the radius is approximately 7.67 cm.
Divide the area by pi and then square root it this will give the radius of the circle.
If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.
You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
It depends on what information you have: the radius and the area of the sector or the length of the arc.

The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
To find the radius of the circle, we first need to determine the radius of the sector. The area of a sector is given by the formula A = 0.5 * r^2 * θ, where A is the area, r is the radius, and θ is the central angle in radians.

Solving for r, we find that the radius is approximately 7.67 cm.
The area of a sector which subtends an angle of x degrees at the centre is given byA = pi*r^2*x/360so r^2 = 360*A/(pi*x) and then r = sqrt{360*A/(pi*x)}
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
Divide the area by pi and then square root it this will give the radius of the circle.
If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.
It depends on what else is known about the sector: length of arc, area or some other measure.
