Question
### Challenge Activity: 2.6.1 Computing an Average **Task:** Write a single statement that assigns `avg_sales` with the average of `num_sales1`, `num_sales2`, and `num_sales3`. **Sample Output with Inputs 3, 4, 8:** ``` Average sales: 5.00 ``` **Code:** ```python 1 avg_sales = 0 2 num_sales1 = int(input()) 3 num_sales2 = int(input()) 4 num_sales3 = int(input()) 5 6 # Your solution goes here 7 8 print('Average sales: {:.2f}'.format(avg_sales)) ``` ### Challenge Activity: 2.6.2 Sphere Volume **Task:** Given `sphere_radius` and `pi`, compute the volume of a sphere and assign `sphere_volume` with the volume. - Formula: Volume of sphere = (4.0/3.0) π r³ --- ### Explanation: - The task in the first challenge is to calculate the average of three inputted numbers (`num_sales1`, `num_sales2`, and `num_sales3`) and store it in the variable `avg_sales`. - In the code snippet, three user inputs are taken and stored as integers in the variables `num_sales1`, `num_sales2`, and `num_sales3`. - The average is calculated by adding these three numbers and dividing by three. - This average is then formatted to two decimal places and printed as "Average sales: 5.00" based on the example given. - The second challenge involves calculating the volume of a sphere using the given formula, which involves using the radius and the mathematical constant π (pi).
