Question

length of arc of circle?​

Answer 1

Hii Mate ☺☺

A practical way to determine the length of an arc in a circle is to plot two lines from the arc's endpoints to the center of the circle, measure the angle where the two lines meet the center, then solve for L by cross-multiplying the statement: measure of angle in degrees/360° = L/circumference.

Answer 2

Answer:

Definition:-

• The distance along the arc (part of the circumference of a circle, or of any curve) is called length of arc and in evaluated by using the formula:

${ { \boxed{\large{\bold\green{length \: of \: arc_{(Circle)}\:l\ = \:\ (2\pi r) \dfrac{θ}{360} }}}}} \:$

Denotations in the Arc Length Formula

• l is the arc length
• r is the radius of the circle
• θ is the central angle of the arc
