R(2πC/360)
C is the central angle of the arc in degrees
R is the radius of the arc
π is Pi, approximately 3.142
the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle
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 it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.
angle of the circle/360 x 2(pi)r
If you have only the arc length then you cannot find the diameter.
the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle
To find the arc length using radians, you can use the formula: Arc Length Radius x Angle in Radians. Simply multiply the radius of the circle by the angle in radians to calculate the arc length.
the fraction of the circle covered by the arc
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.
Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)
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.
It depends on what measure related to the arc you want to find!
angle of the circle/360 x 2(pi)r
To find the arc length, you also need to know the radius (or diameter) of the arc. The arc length is then found by finding the circumference of the full circle (2xPIxradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
divide the measure of the arc by 360
If you have only the arc length then you cannot find the diameter.
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
