Central Angle Measure = (Arc Length * Radius) * 180° Answer The correct answer is:A) Central Angle Measure = (Arc Length / Radius) * 180° Explanation The central angle formula is used to compute the size of a circle's central angle. A central angle is an angle whose vertex is at...
What is Central Angle of Circle Formula? The central angle of a circle formula calculates the angle between two radii of a circle. A central angle can also be defined as an angle subtended by the arc of a circle and the 2 radii at the center of the circle. The radius vectors form the...

When a question asks about the arc, use the formula ((arc))((circumference))=((central angle))(2π) with the measure of the central angle in radians. Since you're literally looking for the fraction of the arc's length to the circumference of the circle, all that is needed to solve...
The arc of a circle: defined and classified as major arc or minor arc. Additionally, how the arc relates to a central angle.
2*pi(如果你取3.14的话）*12=circumference of the whole circle(得到整个圆的周长）=75.36ft 然后圆心角(60/360)*75.36=12.56ft,就这么算
A sector is very similar to a slice of pie or pizza where the vertex is at the center. The area for it needs the radius {eq}(r) {/eq} and the central angle in radians {eq}(\theta ) {/eq}. The formula for the area of a sector of a circle...
C If we let a be the smallest sector angle and r be the difference between consecutive sector angles, then we have the angles a, a+r, a+2r, ⋯. a+11r. Use the formula for the sum of an arithmetic sequence and set it equal to 360, the number of degrees in a circle....
