To derive the arc length formula, let us recall what is the circumference of a full circle whose radius is 'r'. It is 2πr. But arc is just a part (in fact afraction) of the total circumference. We know that the angle at the center in a full circle is 360°. If the angle su...
seen that to add a lot of little bits together is precisely what is called integration, so that it is likely that, since we know how to integrate, we can find also the length of an arc on any curve, provided that the equation of the curve is such that it lends itself to integration...

Measure the length of the chord and the length of the bisecting line segment from the chord to the top of the arc. Step 7 Enter the values into the formula (h/2) + (w^2/8h), where h is the arc height and w is the length of the chord. The result will be the radius. Things...
Remember, the unit circle can be used to find two unknown sides of a right triangle with a 30-degree angle and whose longest side, or hypotenuse, is a length of 7. Let's give it a try. Take note of where 30° is on the unit circle. Use that line and the x-axis to create a...
The circumference of a circle is found by using the formula 2 * 3.14r or 3.14d. To find the length of an arc, multiply the circle's circumference by the arc's angle, then divide by 360 (arc angle / 360). Arc length = (arc length * (3.14d) / 360 or (arc length * 2 * 3.14...
Now we will find the distance between two points A and B on a curve defined by a function f(x) on a closed interval [a,b]. To find this distance we should use the formula s =The integral, between the lower limit, a, and the upper limit, b, of the integrand √(1 +[f'(x)...

Given two circles with radii 4cm and 2cm, and the distance between their centres equal to 8cm, find the length of the common tangent to the circles. Common Tangent: A tangent to a circle is a line that touches the circle at only one point on its circumference. When the same line ...
