7.I have a doubt about on whether it is possible to integrate logarithmic spirals to find the area of certain ...

certain objects. So in this case, I derived a log spiral equation in polar coordinates to model an spiral galaxy. I plan on finding the area as well as volume of the galaxy using the function which I have derived. So is there any way, I could integrate these spiral functions to find area?
