Radius of Circle given Arc Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radius of Circle = Arc Length of Circle/Central Angle of Circle
r = l_Arc/∠_Central
This formula uses 3 Variables

Variables Used

Radius of Circle - (Measured in Meter) - Radius of Circle is the length of any line segment joining the center and any point on the Circle.
Arc Length of Circle - (Measured in Meter) - Arc Length of Circle is the length of a piece of curve cut from the circumference of the Circle at particular central angle.
Central Angle of Circle - (Measured in Radian) - Central Angle of Circle is an angle whose apex (vertex) is the centre O of a Circle and whose legs (sides) are radii intersecting the circle in two distinct points.

STEP 1: Convert Input(s) to Base Unit

Arc Length of Circle: 15 Meter --> 15 Meter No Conversion Required
Central Angle of Circle: 170 Degree --> 2.9670597283898 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r = l_Arc/∠_Central --> 15/2.9670597283898

Evaluating ... ...

r = 5.05550995703763

STEP 3: Convert Result to Output's Unit

5.05550995703763 Meter --> No Conversion Required

FINAL ANSWER

5.05550995703763 ≈ 5.05551 Meter <-- Radius of Circle

What is a Circle?

A Circle is a basic two dimensional geometric shape which is defined as the collection of all points on a plane which are in a fixed distance from a fixed point. The fixed point is called the center of the Circle and the fixed distance is called the radius of the Circle. When two radii become collinear, that combined length is called the diameter of the Circle. That is, diameter is the length of the line segment inside the Circle which pass through the center and it will be two times the radius.
