Hi all.

In Formulas question type, in algebraic answer, I haven't been able to put pi symbol. So I define a variable

Pi = pi()

and I put the instructions as "write Pi ...", and the student has tu put, for example,

Circle area = Pi * r^2 .

Do you know a way to write <pi symbol> in this question type. Thanks
