The length of the arc is equal to the radius times the angle (angle in radians). If the angle is in any other measure, convert to radians first. (radians = degrees * pi / 180)

How do you calculate a segment of an arc on a circle?

Determine the angle opposite the arc and divide by 360. Multiply that by the radius and double the resulting quotient. Multiply by pi. This is the length of the arc.


How to find a sector area in a circle if you have only the arc length?

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.


What is the arc length if the length of the arc is 95 degrees?

Find the circumference of the whole circle and then multiply that length by 95/360.


How do you find the arc length of a circle that has an inscribed polygon?

What do you mean by "arc length of a circle"? If you mean the arc length between two adjacent vertices of the inscribed polygon, then: If the polygon is irregular then the arc length between adjacent vertices of the polygon will vary and it is impossible to calculate and the angle between the radii must be measured from the diagram using a protractor if the angle is not marked. The angle is a fraction of a whole turn (which is 360° or 2π radians) which can be multiplied by the circumference of the circle to find the arc length between the radii: arc_length = 2πradius × angle/angle_of_full_turn → arc_length = 2πradius × angle_in_degrees/360° or arc_length = 2πradius × angle_in_radians/2π = radius × angle_in_radians If there is a regular polygon inscribed in a circle, then there will be a constant angle between the radii of the circle between the adjacent vertices of the polygon and each arc between adjacent vertices will be the same length; assuming you know the radius of the circle, the arc length is thus one number_of_sides_th of the circumference of the circle, namely: arc_length_between_adjacent_vertices_of_inscribed_regular_polygon = 2πradius ÷ number_of_sides


What is the number of degrees in an arc of a circle?

It depends on the length of the arc because there are a total of 360 degrees in a complete circle.

How do you calculate the the arc of a sector?
