Why does this equation return this value? JAVA

Question

It should be returning the value of 70.28, but it returns 0.0. I don't understand why it does this. The equation is set up. I had it set in a method, but I took it out so I can keep those values and use them later on. It worked inside the method, but now that it's out of the method it doesn't work.
