import math
radius = float(input("Enter the radius of the cylinder (in units): "))
height = float(input("Enter the height of the cylinder (in units): "))
lateral_surface_area = 2 * math.pi * radius * height
total_surface_area = 2 * math.pi * radius * (radius + height)
print("The Lateral Surface Area of the cylinder is: ", round(lateral_surface_area,
2), " square units.")
print("The Total Surface Area of the cylinder is: ", round(total_surface_area, 2),
" square units.")

The output of the preceding program is as follows:
Output

Enter the radius of the cylinder (in units): 10
Enter the height of the cylinder (in units): 20
The Lateral Surface Area of the cylinder is: 1256.64 square units.
The Total Surface Area of the cylinder is: 1884.96 square units.
