The formulas for finding arc length utilize the circle’s radius. Since the radius is half the diameter of a circle, to find the radius, simply divide the diameter by 2. For example, if the diameter of a circle is 14 cm, to find the radius, you would divide 14 by 2: 14÷2=7{\displaystyle 14\div 2=7}.

Answer : 3.67 cm. Find the length of an arc with radius 14 cm and central angle 60 degrees? Step 1 : Here, radius = 14 cm central angle = 60 degrees. Step 2 : Length of an arc = 2 × π × r × $\frac{central angle}{360}$ = 2 × π × 14 × $\frac{60}{360}$ = 14.67 cm.

The formula for the arc length of a circle: Arc length of a circle in radians: A sector of a circle: A sector of a circle is a pie shaped portion of the area of the circle. Technically, the piece of pie is between two segments coming out of the center of the circle. The area of a sector of a circle:

A connected section of the circumference of a circle. Arcs are measured in two ways: as the measure of the central angle, or as the length of the arc itself. Measurement by central angle. (degrees) The red arc (minor arc) measures 120°. The blue arc (major arc) measures 240°.

The unit circle. Since in any circle the same ratio of arc to radius determines a unique central angle, then for theoretical work we often use the unit circle, which is a circle of radius 1: r = 1. In the unit circle, the radian measure is the length of the arc s. The length of that arc is a real number x. s = rθ = 1· x = x.

how to find circle arc length
Arc Length of a Circle is equal to the multiplication of 2, central angle divide by 360, Pi, and Radius of arc. The arc length of a circle is 2 multiply by pi multiply by r into central angle divided by 350, where, r is the radius of arc.
