Question

PARTICIPATION ACTIVITY 4.1.13: Hierarchical function calls. Complete the calc_pizza_calories_per_slice() function to calculate the calories for a single slice of pizza. A calc_pizza_calories() function returns a pizza's total calories given the pizza diameter passed as an argument. A calc_num_pizza_slices() function returns the number of slices in a pizza given the pizza diameter passed as an argument def calc pizza_calories_per_slice(pizza_diameter): total_calories = calories_per_slice = return calories_per_slice 1) Type the expression for placeholder_A to calculate the total calories for a pizza with diameter pizza diameter Incorrect calc_pizza_calories(?) total_calories = pizzaCalories(pizzaDiameter); Check Show answer 2) Type the expression for placeholder_B to calculate the calories per slice. Incorrect total calories/? calories_per_slice = total calories / pizza Slices(pizza diameter) Check Show answer Feedba

Answer 1

Placeholder expressions:

Placeholder A: calc_pizza_calories(pizza_diameter)

Placeholder B: total_calories / calc_num_pizza_slices(pizza_diameter)

How to explain

Placeholder A: calc_pizza_calories(pizza_diameter) calls the calc_pizza_calories function with the pizza_diameter argument, retrieving the total calorie count for the entire pizza.

Placeholder B: total_calories / calc_num_pizza_slices(pizza_diameter) divides the total calories by the number of slices in the pizza (calculated by calc_num_pizza_slices(pizza_diameter)) to obtain the calorie count per slice.
