Circumradius of Pentagon given side and central angle Solution

STEP 0: Pre-Calculation Summary
Formula Used
circumradius = (Side)/(2*sin(Central Angle/2))
rc = (S)/(2*sin(Anglecentral/2))
This formula uses 1 Functions, 2 Variables
Functions Used
sin - Trigonometric sine function, sin(Angle)
Variables Used
Side - The side is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (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
Side: 9 Meter --> 9 Meter No Conversion Required
Central Angle: 45 Degree --> 0.785398163397301 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
rc = (S)/(2*sin(Anglecentral/2)) --> (9)/(2*sin(0.785398163397301/2))
Evaluating ... ...
rc = 11.7590666838895
STEP 3: Convert Result to Output's Unit
11.7590666838895 Meter --> No Conversion Required
FINAL ANSWER
11.7590666838895 Meter <-- Circumradius
(Calculation completed in 00.016 seconds)
