Your program in python must produce the correct results for valid inputs. However, it is not expected to handle
invalid inputs (such as negative values). Thus, it is unnecessary to use selective or repetitive control
statements (ifs and loops) in your program.
The formula for the area A of a circle is A = arwhere r denotes the radius. For this calculation, you will
use the value of it provided in the Python math module. After importing the math module, the name
math. pi represents a close approximation to the value of a.
To estimate the number of plants needed for a flowerbed, divide the area of the flowerbed by the area
needed per plant (the square of the recommended distance between plants) and then truncate this result.
To truncate a value of type float, convert it to a value of type int (using the int function).
The program named example. py that is attached contains example usages of many of the Python
features you will use in this project (with explanations in the comments)
