Write a class for both the surface area and volume thanks

C++ Functions (20 points) Write a program to calculate a volume and side surface of a cylinder with a given radius and length respectively . Write a function for each calculation. Display the results in a readable format with two decimal points. Below shows information on how to calculate the volume and the side surface of a cylinder, and how the function should be designed. Volume of cylind er The volume, V, of a cylinder is given by this formula; r is the cylinder's radius, and L is its length. Using this formula, write a C++ function named cylvol) that accepts a cylinder's radius and length and return its volume. Surface area The side surface area, S, of a cylinder is given by this formula r is the cylinder's radius, and 1 is its length. Using this formula, write a C++ function named surfarea() that accepts a cylinder's radius and length and return its side surface area
