Trying to calculate circular surface area – please help

  • I have two questions: I need to calculate the surface area of a circle using the radius. It’s not clear on your documentation how to add pow() sum

    ALso on your youtube video you mention being able to assign a numerical value to a check box (Like I need for the 5% coverage boxes) however, this function no longer works in contact form 7 unless I add it as a value to the checkbox which doesn’t look right.

    Please help.

    I have tried

    [calculator calculator-433 Precision:2 “((radius * radius) * 3.141592653589793238)” * radius5per]

    And it comes up with a warning window “Please enter valid formula in calculator”

    Please help.
