Please help!

Question:
If a significant sample correlation r = -.79, what proportion of the variation in the dependent variable can be explained by the variation in the independent variable.

My work:

-0.79^2= -.6241


Not sure if that is the way to do it....please help!!

How can squaring a real number give a negative answer?
