Circumradius of Pentagon given height and central angle Solution

STEP 0: Pre-Calculation Summary
Formula Used
circumradius = (Height)/(1+cos(Central Angle/2))
rc = (h)/(1+cos(Anglecentral/2))
This formula uses 1 Functions, 2 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
Variables Used
Height - Height is the distance between the lowest and highest points of a person standing upright. (Measured in Meter)
Central Angle - 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. (Measured in Degree)
STEP 1: Convert Input(s) to Base Unit
Height: 12 Meter --> 12 Meter No Conversion Required
Central Angle: 45 Degree --> 0.785398163397301 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
rc = (h)/(1+cos(Anglecentral/2)) --> (12)/(1+cos(0.785398163397301/2))
Evaluating ... ...
rc = 6.23739677937939
STEP 3: Convert Result to Output's Unit
6.23739677937939 Meter --> No Conversion Required
FINAL ANSWER
6.23739677937939 Meter <-- Circumradius
(Calculation completed in 00.000 seconds)
