## What is circumscribed circle and how its radius is calculated when circumscribed in an equilateral triangle ?

In geometry, the circumscribed circle or circumcircle of an equilateral triangle is a circle that passes through all the vertices of the equilateral triangle. The center of this circle is called the circumcenter and its radius is called circumradius. In an equilateral triangle, all three sides are equal in length and all angle measures 60 degrees. Its formula is R = a / √3 where R is the radius of the circumscribed circle of the equilateral triangle and a is the side of the equilateral triangle.

## How to Calculate Radius of the circumscribed circle of an equilateral triangle?

Radius of the circumscribed circle of an equilateral triangle calculator uses Radius Of Circumscribed Circle=Side/sqrt(3) to calculate the Radius Of Circumscribed Circle, Radius of the circumscribed circle of an equilateral triangle is the length of the radius of the circle that passes through all the vertices of the isosceles triangle. The center of this circle is called the circumcenter and its radius is called circumradius. Radius Of Circumscribed Circle and is denoted by r symbol.

### FAQ

What is Radius of the circumscribed circle of an equilateral triangle?
Radius of the circumscribed circle of an equilateral triangle is the length of the radius of the circle that passes through all the vertices of the isosceles triangle. The center of this circle is called the circumcenter and its radius is called circumradius and is represented as r=s/sqrt(3) or Radius Of Circumscribed Circle=Side/sqrt(3). 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.
How to calculate Radius of the circumscribed circle of an equilateral triangle?
