# Exercise 2.1: Finding the Square Root
# math.sqrt(x) returns the square root of x.

# Exercise 2.2: Using Mathematical Constants
# The math module also contains constants like Pi.

# Let's calculate the circumference of a circle with a radius of 5
radius = 5
circumference = 2 * math.pi * radius
print(f"The circumference of a circle with radius {radius} is {circumference:.2f}") # .2f formats to 2 decimal places

# YOUR CODE HERE - Calculate the diagonal of a square.
# The formula is: diagonal = side * sqrt(2)
# 1. Create a variable `side_length` and set it to 10.
# 2. Use math.sqrt() to calculate the diagonal.
# 3. Print the result.
