Area of Pentagon given Circumradius using Central Angle Solution

STEP 0: Pre-Calculation Summary
Formula Used
Area of Pentagon = (5*(Circumradius of Pentagon*sin(pi/5))^2)/tan(pi/5)
A = (5*(rc*sin(pi/5))^2)/tan(pi/5)
This formula uses 1 Constants, 2 Functions, 2 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Functions Used
sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
Variables Used
Area of Pentagon - (Measured in Square Meter) - The Area of Pentagon is the amount of two-dimensional space taken up by a Pentagon.
Circumradius of Pentagon - (Measured in Meter) - The Circumradius of Pentagon is the radius of a circumcircle touching each of the vertices of Pentagon.
STEP 1: Convert Input(s) to Base Unit
Circumradius of Pentagon: 9 Meter --> 9 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A = (5*(rc*sin(pi/5))^2)/tan(pi/5) --> (5*(9*sin(pi/5))^2)/tan(pi/5)
Evaluating ... ...
A = 192.588944549769
STEP 3: Convert Result to Output's Unit
192.588944549769 Square Meter --> No Conversion Required
192.588944549769 192.5889 Square Meter <-- Area of Pentagon

What is Pentagon?

A Pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a five-sided polygon with five straight sides and five interior angles, which add up to 540°. Pentagons can be simple or self-intersecting. A simple pentagon (5-gon) must have five straight sides that meet to create five vertices but do not intersect with each other. A self-intersecting regular pentagon is called a pentagram.
