One way to consider the value of a pizza is to determine how much the pizza costs per square inch. In order to find this cost, you need to determine the area of the pizza, which can be
found by using the formula Area = Tr?. As long as you know the price and diameter of the
pizzas, you can find out which restaurant offers the best value.
(a) Write the function float area(float diameter) that calculates and returns a area per
square inch of a pizza. NB: radius = diameter

(b) The cost per square inch is determined by dividing the pizza's price by the number of
square inches (that is, its area). Write a main function that uses the area function
to calculate the cost per square inch of pizza from 7 different restaurants and print the
restaurant which offers the best value pizza and the restaurant which offers the worst
value pizza. The price and diameter are stored in a two-dimensional array as shown
below.
