Converting from C++ language to C

Hi guys. I want your help to convert this program from c++ to c language

The question is :-A manufacturer wishes to determine the cost of producing an open-top cylindrical
container. The surface area (of the container is the sum of the area of
the circular base plus the area of the outside (r2
+2rh).
Write a program to read the radius of the base r, the height of the container h, the
cost per square centimeter of the material (cost) and the number of containers to be
produced (Quantity) from the user. You should calculate the cost of each container
and the total cost of producing all the containers and print the results on screen.

#include using namespace std; int main() double radius; double height; double cost; int nContainers; double SA; double costContainer; double costAll; float pi = 3.14159265; cout << "Enter the radius of the base (in inches): "; cin >> radius; cout << "Enter the height of the container (in inches): "; cin >> height; cout << "Enter the cost of each container per square centimeter: $"; cin >> cost; cout << "Enter the number of containers to be produced: "; cin >> nContainers; double Radius = radius 2.54; double Height = height 2.54; SA = pi Radius Radius + 2 pi Radius Height; costContainer = SA cost; costAll = costContainer * nContainers; cout << nContainers << " container(s) at $" << cost << " per square centimeter will cost $" << costContainer << " each." << endl; cout << "The grand total for " << nContainers << " containers is $" << costAll << "." << endl; return 0;
