D Untitled lab4 1 7 of 8 140% >> Exercise 4 (.../40) The total surface area of a right-circular cone (a right cone with a base that is a circle) can be calculated by the function: f:h,r + f(h,r); f(h,r) = Ter? + ner x Vp2 + h? = where h is the height of the cone and r is the radius of the circular base. Step 1: We will continue adding code to this same file, lab4.py Step 2: Under the other function definitions (but above the main script), type this function header: def area_of_cone(height, radius): This function will return the total area of a circular cone (base + lateral area) with the specified non-negative height and radius. Write the body of the function to complete the function definition. For the value of a, use variable pi from the math module. Python's math module also has a function that calculates square roots. To find out about this function, use Python's help facility. In the shell, type: >>> import math >>> help(math.sqrt) Step 3: Save the code, then click Run. Correct any syntax errors
