    Help squaring a variable

    I want to square a variable. Please help me.Here is my code:

    code:

    decimal number1 = Convert.ToInt32(textBox1.Text);
    double pi = Math.PI;
    double Radius_to_Circumference = (double)number1 * 2 * pi;
    double RTD = (double)number1 * 2;
    double RTA = (double)Math.Pow(number1, 2) * pi;
    MessageBox.Show("The circumference is " + Radius_to_Circumference + " \nThe Diameter is " + RTD + " \nThe Area is " +;

    Re: Help squaring a variable

    Once again, you have not explained what the problem is. We are not your debuggers. Take some time and explain exactly what is going wrong instead of throwing some code at us and saying "make it work".

    The program is made to tell you all the info of a circle by only putting in the area,radius,circumference or diameter
    The problem is here:
    double RTA = (double)Math.Pow(number1, 2) * pi;

    I wrote this afterwad and it worked:
    private void button2_Click(object sender, EventArgs e)
    {
    decimal number = Convert.ToInt32(textBox2.Text);
    double pi = Math.PI;
    double DTR = (double)number / 2;
    double DTC = (double)number * pi;
    double DTR2 =(double) number / 2;
    This is the part: double DTA = (double)Math.Pow(DTR2, 2) * pi;

    Math.Pow already returns a double, the cast is redundant.
