To calculate the arc length of a sector:
calculate the circumference length, using (pi * diameter), then multiply by (sector angle / 360 degrees)
so : (pi * diameter) * (sector angle / 360) = arc length
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
sector
how
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 a sector has an angle of 118.7 and an arc length of 58.95 mm its radius is: 28.45 mm
If it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.
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.
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
Is a SECTOR. or SEGMENT.
sector
The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm
how
a sector is a portion of a circle bounded by the two radii and the included arc.
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 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.
