CircleClass Function

[bug2207]

I am confused about how to continue with this function. I'm not asking for the code just a bit of direction as to how I should continue.

#include<iostream.h>
#include<lvp\string.h>
#include"StringUtility.h"
#include<lvp\CIRCLE.h>
#include<math.h>
int main()
{
	CircleClass tire(17);
	cout<<getVolume();//don't know what to put here
	return(0);
}
//----------------------------------------------------------------------------
double getVolume(const CircleClass &obj)
/*Determines the volume of the sphere based upon the Circle object parameter*/
{
	int Radius;
	obj.SetRadius(Radius);
	return (double(4/3)*double(3.14*(pow(Radius,3))));
}
