write a c++ program

Given some number n = 17.3 cm. Write a program that uses n as the radius of a circle. Compute and print the circumference and area of the circle. Convert n to inches and compute and print the area an circumference again. Let n be the radius of a sphere. Compute and print the volume of the sphere. Convert n to inches and compute the volume print again. Let n be the side of a square. compute and print the perimeter and area of the square. Convert n to inches and compute and print again. Let n be the side of a cube. Compute the surface area and volume of the cube. Convert to n inches and compute and print again.
