        {
            //declaring variables
            double inp_based = 0;

            double pi = 3.14;
            double volume = 0;
 
 
            //passing the value of a textbox in the variables
            inp_based = double.Parse(txtBase.Text);
            inp_height = double.Parse(txtHieght.Text);
 
            // Set the formula to get the volume of a cylinder
            volume = ((inp_based * inp_based) * inp_height) * pi;
 
            //displaying the result
            txtOutput.Text = "The volume of a cylinder is : " +  volume.ToString() + " m3";
        }
