Data Types and Var_Cone

//--------------------------------------
// Write a function to calculate a cone’s volume and total surface area by given height and radius at the base.
// The input comes as two number arguments. The first element is the cone’s radius and the second is its height.
// The output should be printed to the console on a new line for every result.
// The result should be formatted to the fourth decimal point
//--------------------------------------
