## Radius of the circumcircle of a triangle using semiperimeter Solution

STEP 0: Pre-Calculation Summary
Formula Used
radius = ((Side A)*(Side B)*(Side C))/4*(sqrt(Semiperimeter*(Semiperimeter-Side A)*(Semiperimeter-Side B)*(Semiperimeter-Side C)))
r = ((a)*(b)*(c))/4*(sqrt(S*(S-a)*(S-b)*(S-c)))
This formula uses 1 Functions, 4 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Side A - Side A 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. (Measured in Meter)
Side B - Side B 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. (Measured in Meter)
Side C - Side C 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. (Measured in Meter)
Semiperimeter - Semiperimeter of an isosceles triangle is half of the sum of length of all sides. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Side A: 8 Meter --> 8 Meter No Conversion Required
Side B: 7 Meter --> 7 Meter No Conversion Required
Side C: 4 Meter --> 4 Meter No Conversion Required
Semiperimeter: 10 Meter --> 10 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
r = ((a)*(b)*(c))/4*(sqrt(S*(S-a)*(S-b)*(S-c))) --> ((8)*(7)*(4))/4*(sqrt(10*(10-8)*(10-7)*(10-4)))
Evaluating ... ...

## What is a circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called center. The different parts of a circle are radius, diameter, chord, tangent, arc, center, secant, sector. The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
