To find arc length, start by dividing the arc’s central angle in degrees by 360. Then, multiply that number by the radius of the circle. Finally, multiply that number by 2 × pi to find the arc length.Click to see full answer. Regarding this, what is the length of arc XPY in terms of pi?30π m.Additionally, what is the area of the given circle in terms of pi? Area of a circle. The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter. Also, what is the formula of arc length? How To Find Arc Length. You need to know the measurement of the central angle that created the arc (the angle of the two radii) to calculate arc length. The arc length is the fractional amount of the circumference of the circle. The circumference of any circle is found with 2πr 2 π r where r = radius r = r a d i u s .What is arc length equal to?Arc Measure: In a circle, the degree measure of an arc is equal to the measure of the central angle that intercepts the arc. Arc Length: In a circle, the length of an arc is a portion of the circumference. One radian is the central angle that subtends an arc length of one radius (s = r).
