### Formula name

HERON FORMULA

### Description

area and circumscribed circle of any triangle

### Syntax

s = (a + b + c) / 2

/* "s" means the half of the periphery of any triangle with its sides a, b and c and with the area "A". */

A = SQRT( s*(s - a)*(s - b)*(s - c))

R = a * b * c / (4 * A)

/* "R" means the radius of the circumscribed circle. */

/* "s" means the half of the periphery of any triangle with its sides a, b and c and with the area "A". */

A = SQRT( s*(s - a)*(s - b)*(s - c))

R = a * b * c / (4 * A)

/* "R" means the radius of the circumscribed circle. */
