Pi in Scilab

Scilab, a robust computational platform, allows the integration of the mathematical constant π (pi) - which represents the ratio of a circle's circumference to its diameter - into your mathematical undertakings. It's as simple as invoking the constant %pi.

%pi

Now, let's dive into a practical scenario.

First, we'll assign the radius of a circle to a variable we'll name 'radius'. Let's suppose it's a circle with a radius of 5 units.

radius = 5;

With our 'radius' defined, we can then move to compute the circumference of our circle. The formula to be deployed here is c=2πr.

circumference = 2 * %pi * radius;

In this application, %pi seamlessly slides into the role of our essential constant, allowing us to compute the circumference of a circle with a radius of 5 units.

The culmination of this calculation presents us with the circumference of our circle.

31.4

So, for a circle where the radius is r=5, we find that the circumference is c=31.4 units.

A visual breakdown of the calculation follows:

$$ c = 2 \cdot \pi \cdot r $$

$$ c = 2 \cdot 3.14 \cdot 5 $$

$$ c = 10 \cdot 3.14 $$

$$ c= 31.4 $$
