SEARCH THIS SITE

An online calculator to calculate the radius R of a circumscribed circle of a triangle of sides a, b and c.

triangle with sides a, b and c and circumscribed circle of radius R

This calculator uses the formula

2R = a / sin A = b / sin B = c / sin C

How to use the calculator

Enter the sides a, b and c of the triangle as positive real numbers and press "enter". The output is the radius of the circumscribed circle. If one of the sides of the triangle is negative or the sum of any two sides is smaller that the third one (i.e the triangle does not exist), the message " not valid " is displayed.
