## Radius of Circle from Arc Angle and Arc Length Solution

STEP 0: Pre-Calculation Summary
Formula Used
r = s/θ
This formula uses 2 Variables
Variables Used
Arc Length - Arc length is the distance between two points along a section of a curve. (Measured in Meter)
Subtended Angle in Radians - Subtended Angle in radians is the angle made by something from a given viewpoint. (Measured in Degree)
STEP 1: Convert Input(s) to Base Unit
Arc Length: 2.4 Meter --> 2.4 Meter No Conversion Required
Subtended Angle in Radians: 3.14 Degree --> 0.0548033385126116 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
r = s/θ --> 2.4/0.0548033385126116
Evaluating ... ...
r = 43.7929524940839
STEP 3: Convert Result to Output's Unit
43.7929524940839 Meter -->4379.29524940839 Centimeter (Check conversion here)
4379.29524940839 Centimeter <-- Radius of circle
