Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees

The answer depends on what information you do have: radius, arc length, central angle etc.

If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)

That will depend on the length of its arc which has not been given

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.

A=25-(r-5)(r-5)→10-r2(Length of Arc) + (2*radius) = Perimeter of Sector→rӨ+2r=20so Length of Arc,rӨ=20-2rArea of sector=½rӨ=rӨ(½r)Sub length of arc equation into area of sector equation gives: (20-2r)(½r)=10-r2Thus it is proved.

If a sector has an angle of 118.7 and an arc length of 58.95 mm its radius is: 28.45 mm

The arc length of a sector that is 125 degrees and has a radius of 20 inches is: 43.63 inches.

The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.

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

The answer depends on what information you do have: radius, arc length, central angle etc.

There is no direct relation between the area of a sector and the length of an arc. You must know the radius (or diameter) or the angle of the sector at the centre.

If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)

It depends on what else is known about the sector: length of arc, area or some other measure.
