Question: 
Write a function to find the lateral surface area of a cylinder.


Model's Code:
def lateralsuface_cylinder(radius, height):
    import math
    return 2 * math.pi * radius * height



Sample Correct Code:
def lateralsuface_cylinder(r,h):
  lateralsurface= 2*3.1415*r*h
  return lateralsurface


Asserts:
assert lateralsuface_cylinder(10,5)==314.15000000000003
assert lateralsuface_cylinder(4,5)==125.66000000000001
assert lateralsuface_cylinder(4,10)==251.32000000000002
