Circumradius of Pentagon given Height using Central Angle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Circumradius of Pentagon = (Height of Pentagon)/(1+cos(pi/5))
r_c = (h)/(1+cos(pi/5))
This formula uses 1 Constants, 1 Functions, 2 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

Circumradius of Pentagon - (Measured in Meter) - The Circumradius of Pentagon is the radius of a circumcircle touching each of the vertices of Pentagon.
Height of Pentagon - (Measured in Meter) - Height of Pentagon is the distance between one side of Pentagon and its opposite vertex.

STEP 1: Convert Input(s) to Base Unit

Height of Pentagon: 15 Meter --> 15 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_c = (h)/(1+cos(pi/5)) --> (15)/(1+cos(pi/5))

Evaluating ... ...

r_c = 8.29179606750063

STEP 3: Convert Result to Output's Unit

8.29179606750063 Meter --> No Conversion Required

FINAL ANSWER

8.29179606750063 ≈ 8.291796 Meter <-- Circumradius 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.
