Question

Exercise 2.2. Practice using the Python interpreter as a calculator: 1. The volume of a sphere uith radius r is rs. What is the volume of a sphere with radius 5? 2. Suppose the cover price of a book is $24.95, but bookstores get a 40% discount. Shipping costs $3 for the first copy and 75 cents for each additional copy. What is the total wholesale cost for 60 copies? . If I leave my house at 6:52 am and run 1 mile at an easy pace (8:15 per mile), then 3 miles at tempo (7:12 per mile) and 1 mile at easy pace again, what time do Iget home for breakfast?

Answer 1

In order to run the below queries, open Python console and then type the following statements.

CODE

==============

import math

radius = 5.0

print((4 * math.pi * (radius ** 3))/3)

cover_price = 0.6 * 24.95

total_cost = cover_price * 60 + (3 * 59*.75)

print(total_cost)

NOTE: I did not understand part 3. Hence, I have skipped it. What is 8:15 per mile?
