STEP 0: Pre-Calculation Summary

Formula Used

Proportionate perimeter = (Central Angle/(360*pi/180))
P_p = (∠_central/(360*pi/180))
This formula uses 1 Constants, 2 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Proportionate perimeter - Proportionate perimeter is the ratio of perimeter while running partially full to running full.
Central Angle - (Measured in Radian) - A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B.

STEP 1: Convert Input(s) to Base Unit

Central Angle: 45 Degree --> 0.785398163397301 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_p = (∠_central/(360*pi/180)) --> (0.785398163397301/(360*pi/180))

Evaluating ... ...

P_p = 0.124999999999977

STEP 3: Convert Result to Output's Unit

0.124999999999977 --> No Conversion Required

FINAL ANSWER

0.124999999999977 ≈ 0.125 <-- Proportionate perimeter
