Relational expressions are used to compare two data values, typically using operators like <, >, ==, etc.

Question 5

Case Study 1:
>>> import math
>>> numSides = 8
>>> innerAngleB = 360.0 / numSides
>>> halfAngleA = innerAngleB / 2
>>> oneHalfSideS = math.sin(math.radians(halfAngleA))
>>> sideS = oneHalfSideS * 2
>>> polygonCircumference = numSides * sideS
>>> pi = polygonCircumference / 2
>>> pi
