Question

Problem1. James goes to restaurant for dinner. The items he orders are soup for $3.99, sandwich for $5.99 and a drink for $2.99, peach cobbler for $4.99. Calculate the subtotal, gratuity and total if the gratuity rate is 20%.

Problem2. Write a program which reads in an integer from the user and then prints out the last digit of the number that is 4 times the value which the user entered.

For example, if a user enters the number 52 , your program will compute the number 4*52=208 and print out the last digit which is 8.

Note: Use the modulo operator (%)

Problem3. Compute the volume of cylinder if the radius of the cylinder is 9 and length is 16. Assume the value of “pi” as 3.1415. Use the formula given below.

area = radius *radius*pi

volume = area *length

Answer 1

Answer 1:

subtotal=3.99+5.99+2.99+4.99

gratuity=subtotal*0.2

total=subtotal+gratuity

print("Sub total: ",subtotal)

print("Gratuity: ",gratuity)

print("Total: ",total)

Answer 2:

num=int(input("Enter number: "))

#adding 4 times

num=num*4

#printing last digit

print("Last digit: ",(num%10))

radius=9

length=16

pi=3.1415

#finding area

area = radius *radius*pi

#finding volume

volume = area *length

print("Area: ",area)

print("Volume: ",volume)
