Calculate Surface Area and Volume of Can

A soda can is designed to maximize volume while minimizing surface area (i.e. material). Write a function, called can_specs, that calculates the properties of a can. The function should have two inputs; first, the radius of the can and second, the height of the can. The function should return two values; first, the surface area of the can and second, the volume of the can. The equation of the surface area of a can is: The equation for the volume of the can is:
