For example, let’s say you have a circle with a radius of 5 feet and a central angle of 1 radian. Plugging those values into the formula gives you an arc length of 5 feet. If you don’t know the radius or central angle, you can still find the arc length by approximating the cur...

We know that a circle is a very important two-dimensional shape in geometry. There is a term “arc” is used with reference to the circle. In this article, we will see the details about the arc and computation of the arc length formula with examples. Let
What is the formula for arc length of a sector? The formula to find the arc length of a sector is as follows: {eq}s=r\theta {/eq}, where you would need the length of the radius between the endpoint of the arc and the center of the circle, and the angle's measure in radians....
For example, if the arc length of a circle is given as 15 cm and the area of the sector is 225 cm2. We know that, Area of sector = (Arc length × radius)/2. After substituting the values in this formula, we get, 225 = (15 × radius)/2. This can be further solved as, (...
Arc length formula is given here in normal and integral form. Click now to know how to calculate the arc length using the formula for the length of an arc with solved example questions.
Are you a student or a teacher? FAQ What is the formula for the length of an arc? If the subtended angle is given in radians, the formula for arc length is s=r*theta, where "s" is the arc length, "r" is the radius of the circle, and "theta" is the subtended angle. If the...
