Circumradius of Equilateral Triangle Calculator

Calculate Circumradius



Formula

The formula to calculate the Circumradius of an Equilateral Triangle is:

\[ r_c = \frac{l_e}{\sqrt{3}} \]

Definition

The circumradius of an equilateral triangle is the radius of a circumcircle that touches each of the triangle's vertices. The edge length is the length of one of the sides of the equilateral triangle, where all three sides are equal.

Example Calculation

Let's assume the following value:

Using the formula:

\[ r_c = \frac{8}{\sqrt{3}} \approx 4.61880215351701 \]

The Circumradius is approximately 4.61880215351701 Meters.
