Write a program (in Xcode Playground) to calculate and display the volume and surface area of a right circular cone with a diameter of 2 and a height of 6.5 Use the following approximate value for Pi: 3.14159265359. Create a constant to hold the value of pi and variables to hold the diameter, height, volume, and surface area.
