I need to write a program to calculate time it takes (in increments of 10 seconds) to drain a tank of radius 2ft and height3ft

I have to use a function to get full credit

I am having major trouble, can anyone help?

Code:

#include <iostream>
#include <cstdlib>
#include <cmath>
using namespace std;
//Project 3 - Draining a Tank
//Name function for calculating volume lost
float calcVolLost(int height);
int main (void)
{
const double pi=3.14159;
float volume, VolumeLost, VelocityJet, DiaJet;
int time=0, height=3, RadiusTank=2;
//set flags for formatting
cout.setf(ios::left);
cout.setf(ios::adjustfield);
cout.setf(ios::showpoint);
cout.setf(ios::fixed);
cout.precision(3);
cout <<"Time"<<"Height of Fluid"<<"Velocity of Jet"<<"Diameter of Jet"<<endl;
//Subtract volume lost and calculate new height
while (height <=0){
float calcVolLost(int height);
volume=volume-VolumeLost;
height=height-(volume/(pi*RadiusTank*RadiusTank));
cout<<time<<height<<VelocityJet<<DiaJet<<endl;
}
return EXIT_SUCCESS;
}
//function for calculating volume lost
float calcVolLost(int height) {
i nt time;
const double pi=3.14159;
float c=0.95, float AreaJet, float DiaJet,float VelocityJet, float VolumeLost, float RadiusJet=0.1667;
AreaJet=pi*RadiusJet*RadiusJet;
VelocityJet=sqrt(2*32.2*height);
VolumeLost=10*VelocityJet*c*AreaJet;
time=time+10;
return VolumeLost;
}
