Question

1. Given the radius, in inches, and price of a pizza, write a program to find the price of the pizza per square inch. Use float data type and format to 2 decimal places. You must have a $ sign for the price per square inch. Use math.pi to get the value if PI.  

To do this use:

import math

PI = math.pi

And then use PI to calculate area of pizza. Name your file ws3part1.py. Read the style guidelines before you submit the file.

import math

# Take value of radius of pizza as input from user and store it in variable 'radius'
radius = float(input('Enter radius of the pizza (in inches): '))

# Take value of price of pizza as input from user and store it in variable 'price'
price = float(input('Enter price of the pizza (in dollars): '))

# Store value of pi into variable 'PI'
PI = math.pi

# Calculate area of the pizza and store it in variable 'area'
area = PI*radius*radius

# Calculate price per square inch of pizza and store it in variable 'ppi'
ppi = price/area

# Format the obtained price per square inch to 2 decimal places
ppi = '%.2f' % ppi

# Print the obtained price per square inch of the pizza
print ('The price of the pizza per square inch is $' + ppi)
