''' Challenge: Solar System

Objective: Use the math module to calculate the area of circles (planets) using mathematical constants like pi. '''

# Calculate surface area
area = 4 * pi * r ** 2

# Print the results with rounding
print(f"{random_planet}'s surface area is approximately {round(area)} km²")
