Circumradius of Pentagon given Inradius Solution

STEP 0: Pre-Calculation Summary

Formula Used

Circumradius of Pentagon = (Inradius of Pentagon)/(sqrt(25+(10*sqrt(5)))/sqrt(50+(10*sqrt(5))))
r_c = (r_i)/(sqrt(25+(10*sqrt(5)))/sqrt(50+(10*sqrt(5))))
This formula uses 1 Functions, 2 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

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.
Inradius of Pentagon - (Measured in Meter) - The Inradius of Pentagon is defined as the radius of the circle which is inscribed inside the Pentagon.

STEP 1: Convert Input(s) to Base Unit

Inradius of Pentagon: 7 Meter --> 7 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_c = (r_i)/(sqrt(25+(10*sqrt(5)))/sqrt(50+(10*sqrt(5)))) --> (7)/(sqrt(25+(10*sqrt(5)))/sqrt(50+(10*sqrt(5))))

Evaluating ... ...

r_c = 8.65247584249853

STEP 3: Convert Result to Output's Unit

8.65247584249853 Meter --> No Conversion Required

FINAL ANSWER

8.65247584249853 ≈ 8.652476 Meter <-- Circumradius of Pentagon

(Calculation completed in 00.004 seconds)

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.
