Question
(Compute the volume of a cylinder) Write a program that reads in the radius and length of a cylinder and computes the area and volume using the following formulas:
area = radius * radius * π
volume = area * length
Here is a sample run:
Enter the radius and length of a cylinder: 5.5, 12
The area is 95.0331
The volume is 1140.4
Answer
Executable code:
# Prompt the user to enter a radius
radius,length=eval(input("Enter the radius and length of a cylinder: "))
# Calculate the area
area = radius * radius * 3.14159
#Display the area
print("The area is ",round(area,4))
#Calculate the volume
volume = area * length
# Calculate volume
print("The volume is ",round(volume,1))
