Answer:
The arrange code is as follows:
#include<iomanip>
#include<iostream>
#include<math.h>
using namespace std;
const double PI = 3.14159;
int main(){
double height;
double radius;
cout << "Enter the height of the cylinder: ";
cout << endl;
cin >> height;
cout << "Enter the radius of the base of the cylinder: ";
cout << endl;
cin >> radius;
cout << fixed << showpoint << setprecision(2);
cout << "Volume of the cylinder = "<< PI * pow(radius, 2.0)* height << endl;
cout << "Surface area: "<< 2 * radius * + 2 * PI * pow(radius, 2.0) << endl;
return 0;
}

Rearrange the program
There are no one way to solve questions like this. However, a simple guide is as follows:
All header files must be called first (i.e #include....)
Followed by the namespaces (std)
if the program uses constant, the constant must be declared and initialized.
e.g. const double PI = 3.14159;
Next, all variables and must be declared (e.g. double radius)
Next, all inputs must be taken before the values of the variables can be used (e.g. cin >> height;)
If the inputs used prompts, the prompt must be before the inputs.
Next, perform all computations then output the results
