Write a program that reads from the console a number r and calculates and prints the circle's area and perimeter with radius r.
|3||Area = 28.2743338823081
Perimeter = 18.8495559215388
|4.5||Area = 63.6172512351933
Perimeter = 28.2743338823081
For the calculations you may use the following formulas:
Area = Math.PI * r * r.
Perimeter = 2 * Math.PI * r.
