I presume that you want to use the squared symbol as in superscript of 2.

This is a standard character, so you should set the text property to something like

A²=B²+C²

It is character 0178, so press ALT down and then type 0178 while ALT is pressed

Well my theorem works but my answer is not doubling. When I try to sqr my answer in code, I get errors.

The code would be

Asquared = ( B^2) + (C^2)
A = ASquared ^ 0.5

some languages use ** instead of ^ for power operations

I am using VB to write code. Here is my code so far.

Private Sub btnConvert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnConvert.Click
 
        If Theorem.Checked Then
            'hypothenuse
            txtOutput.Text = Math.Pow(NUDradius.Value, 2) + Math.Pow(NUDheight.Value, 2)
        ElseIf Cylinder.Checked Then
            'cylinder volume
            txtOutput.Text = Math.Pow(NUDradius.Value, 2) * NUDheight.Value * Math.PI
        End If
    End Sub

Your code for the hypothenuse is only calculating the sum of squares, it is not then taking the squareroot of the sum

try something like this

Dim SumofSquares as double =  Math.Pow(NUDradius.Value, 2) + Math.Pow(NUDheight.Value, 2)
 txtOutput.Text =Math.pow(SumofSquares,0.5).tostring("0.000")
