# How to find arc length? (Easy Steps)

##### The arc of a circle is a portion of the circumference of a circle. You can say the circumference of a circle is full around the circle, this the main reason when we are finding the arc of the length, then we multiply the whole circumference by the angle of the circle and dividing The formula for the arc is also derived by multiplying the angle of the arc with the circumference of the circle and dividing the whole formula by 360.

Circular segment length is better characterized as the distance along with the piece of the circuit of any circle or any bend (curve). Any distance along the bent line that makes up the curve is known as the circular segment length. A piece of a bend or a piece of a perimeter of a circle is called Arc. Every one of them has a bend in its shape.

##### The Arc Length Calculator is commonly used to find the arch and there are multiple uses of the arch length. The length of arc calculator is commonly used in the construction industry and historical sites are full of different types of arc.

In this article, we are discussing the step by step method of Arc Length:

**The formula of finding the Arc:**

## The formula for finding the arch of the circle is:

** Arc Length = **2 π r( θ/360)

We can find the length or “r” by using the length of the arc calculator. Then we only have to put the values in the formula

Where r=radius of the circle and the value of ** π**=22/7** **

The length of arc calculator formula would help in finding the exact arc of a circle.

**Step by step procedure of finding the arc length:**

Now for example if we need to find the arc length of a circle of radius=12, and an angle of 45. Then we need to find the arc length and hence the arch sector, we can use the length of arc calculator to find the arch length:

The marking of the angles: First mark all the points of the circle. For example, the center of the circle is marked as “O”, and the arch is marked as “AB”, Now the angle is represented as m<AOB = 45 and the arch mAB. We can use the arc calculator to find the arch length of a circle.

**Putting the values in the formula:**

Now we put the values of the m<AOB = 45 in the arch length formula, to calculate the arch length:

** Arc Length = ****2 π r( θ/360)**** **

Putting the values of the radius and the angle of the arc, which is 12 and 45in the formula,

** Arc Length = ****2 π r( ****45****360****)**** **

First, we would solve the small bracket and (45/360) at first

** Arc Length = ****2 π 12( ****1****8****)**** **

Now by multiplying the values of the radius=12 with “2” we got the result as follows:

** Arc Length = ****24π ( ****1****8****)**** **

Now by cutting the values and multiplying them with the values of the π, we would get the final value of the Arc Length, the Arc Length can be easily collected by the Arc Length Calculator.

** Arc Length =** 9.42 units** **

The arc length is commonly used to solve the various questions of the calculus when there is a circle involved in the question. We can find the arch sector, which is a small portion of a circle.

Utilizing the Pythagorean hypothesis over a huge distance isn’t generally. So exact as utilizing it over a lot more modest distance. Indeed, assuming I take these fragment lengths to be zero, that is accept the breaking point as delta x goes to zero of these portions. I wind up getting the specific length of my way. I likewise wind up getting the cutoff as delta x goes to no. The total over every one of my sections of the square foundation of ((1 + ((delta y)/(delta x))^2)) (delta x). At the point when I take that cutoff, it’s just a Riemann aggregate that I’ve taken the constraint of. This equivalent is the essential from the beginning of my way, a, to the furthest limit of my way, b, of the square base of (1 + (y’)^2)dx. This y’ is simply dy/dx, so that is what befalls this delta y/delta x term as delta x goes to nothing. This quits being the slant of the line and starts turning into the slant of the digression of the line.
