ARC Length Worksheet ARC Length Worksheet In geometrical mathematics, various types of shapes and figures are defined in the Euclidean geometrical plane. A circle can be easily described as a simple geometrical figure which is formed by the collection of several points around the central of the circle. The shape of circle in geometry plays an important role in the real world situation. According to mathematical definition, circle can be specified as a closed surface which is figured by various circumference points around the central point of the circle. In mathematics various types of properties that are related to the circle, are defined. Arc is one of them. An ‘arc’ in geometrical circle, can be defined as a closed frame of a differential segment of a differential curve on the 2 - D planes. In simple language we can define arc as a circular arc, which is considered as a part of circumference of the circle. Know More About Circumference And arc length Worksheets

In traditional way, the letter‘s’ is used to initialize the length of an arc, which is commonly known as arc length. In mathematics, the arc length can be defined as a part of circle. In short we can say that arc length can be calculated when circumference of circle is known because the ratio of the circumference to the diameter is the basis of the radian measure. In general arc length worksheet of a circle can be described with the ‘r’ and ‘θ’. In the given arc length worksheet the symbol ‘r’ is used for denoting the radius of circle and the symbol ‘θ’ is used for denoting the angle of a circle, which is used for measuring an angle in radian with the circle center. Arc length worksheet describe that the central angle of the circle equals to the ‘θ’, because l / c = θ / 2 * pi, Above ‘l’ shows the arc length of a circle and ‘c’ is used for denoting the circumference of the circle. Now by using substitution we can represent the above notation as: l / 2* pi * r = θ / 2 * pi )

(Note: as we know that circumference of circle = 2 * pi * r

Now we can perform the solving process of arc length ‘L’, in terms of ‘θ’ that yields: l = θ, Read More About Applications Of Integration Worksheets

In mathematics, the measure of arc length can be calculated either in the form of unit length or they can also be calculated in the form of degree. The arc length is the portion of the circle, which can be determined by the size of its corresponding central angle. In measure of arc length, the concept of proportion is used that evaluates the part of the circle to the whole circle either in form of degree or in unit measure. Angle / 360 = l / c, Example: Suppose in any question given that the measure of the angle is 90o and the circumference is 24 inches then we need to calculate be the measure of an arc length? Solution: when we proceed to solve the problem then we use the above given formula, which are shown in the following process: Angle / 360 = l / c 90 / 360 = l / 24, 360 * l = 2160, l = 2160 / 360, l = 6.
