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


Model's Code:
def lateralsurface_cone(radius, height):
    import math
    slant_height = math.sqrt(radius**2 + height**2)
    return math.pi * radius * slant_height



Sample Correct Code:
import math
def lateralsurface_cone(r,h):
  l = math.sqrt(r * r + h * h)
  LSA = math.pi * r  * l
  return LSA


Asserts:
assert lateralsurface_cone(5,12)==204.20352248333654
assert lateralsurface_cone(10,15)==566.3586699569488
assert lateralsurface_cone(19,17)==1521.8090132193388
