Area of Circle
Time for the math
library. It has a lot of mathematical methods and numbers. Surprised?
Suppose you wanted to calculate the area of a circle with more precision and you didn't have pi memorized to 100 digits like most people do. You could either start learning about pi... or just use the math
library!
Okay... time to make that hypothetical area of a circle program less hypothetical.
Create a function area_of_circle
that receives the radius
and returns the area of the circle (pi * r * r) using the math
library to get your value for pi.
Examples:
area_of_circle(1) # 3.141592653589793
area_of_circle(2) # 12.566370614359172
