    Default Cannot find symbol?

    hey really strange error...help please.
    this is my code

    import javax.swing.JOptionPane;
     
    class GearPumps
    {
    	public static void main(String[]args)
    	{
     
    	String input1;
    	String input2;
    	String input3;
    	double gearw;
    	double borediameter;
    	double gearchambers;
    	double gpm;
    	double cir;
    	int again;
     
    		do
    		{
    			//This gets the input for the equations.
    			input1 = JOptionPane.showInputDialog("Enter the gear width in Inches.");
    			input2 = JOptionPane.showInputDialog("Enter the Bore Diameter.");
    			input3 = JOptionPane.showInputDialog("Enter the distance across both Gear Chambers.");
     
     
    			//converts the inputed strings to a double
     
    			gearw = Double.parseDouble(input1);
    			borediameter = Double.parseDouble(input2);
    			gearchambers = Double.parseDouble(input3);
     
    			//sets formulas for cubic inch revolution and gallons per minute;
    			gpm =( 47.0 * gearw * ((2.0*borediameter)-gearchambers) * (gearchambers - borediameter)/2);
     
    			cir = (6.0 * gearw ((2.0 * borediameter) -gearchambers) * (gearchambers - borediameter)/2);
     
    			//displays results
    			JOptionPane.showMessageDialog(null,"GPM: "+ gpm  + "CIR: "+cir);
     
     
    			//ask user to go again.
    			again = JOptionPane.showConfirmDialog(null, "Another calculation?");
     
    		}
    		while(again  == JOptionPane.YES_OPTION);
    	}
    }

    and i get this error:
    GearPumps.java:35: cannot find symbol
    symbol : method gearw(double)
    location: class GearPumps
    cir = (6.0 * gearw ((2.0 * borediameter) -gearchambers) * (gearchambers - borediameter)/2);
