    Basic VBA Function to calculate the volume of a cone

    Hello Folks,

    I am trying to write a function that writes a code to calculate the volume of a cone. The function seems alright to me but when using it on excel I keep getting the error #NAME? . I know this must be very basic but can you please help me fixing this? The code is below...

    Function vcone(r As Double, h As Double) As Double
    Dim pi As Double
    pi = 4 * Atn(1)
    vcone = 1 / 3 * pi * r ^ 2 * h
    End Function

    Works for me. What do you get when you bring up the formula wizard?

    This works also


    Option Explicit
    
    
    Function VolCone(r As Double, h As Double) As Double
        Dim Pie As Double
        
        Pie = Application.WorksheetFunction.pi
        
        VolCone = (1 / 3) * Pie * (r ^ 2) * h
    
    
    End Function
