Exercise 5 In this exercise, you'11 leam how we can use function calls as arguments of other function calls. Step 1: Below the comment, \# Exercise 5, type this function header: def distance (x1 : int, y1 : int, x2 : int, y2 : int) float: This function will return the distance between two points, given by the coordinates (x1,y1) and (x2,y2). Step 2: Use the function design recipe presented in the textbook and lectures to complete the function definition. You've been provided with the function header, but must write a complete docstring and the function body. Step 3: Save the code, then click Run. Correct any syntax errors. Step 4: Use the shell and your docstring examples to test distance. Step 5: Type this function header: def area_of_circle(xc: int, yc: int, xp: int, yp: int) float: This function takes the coordinates of two points, the center of a circle (xc,yc), and a point on the perimeter, (xp,yp). It returns the area of the circle. Step 6: Use the function design recipe presented in the textbook and lectures to complete the function definition. You've been provided with the function header, but must write a complete docstring and the function body. area_of_circle must call the area_of_disk function from Exercise 1 and your distance function. Remember, the function body must contain exactly one statement: return followed by an expression. Don't copy and paste code from area_of_disk or distance into area_of_circle. Step 7: Save the code, then click Run. Correct any syntax errors. Step 8: Use the shell and your docstring examples to test area_of_circle
