find the area enclosed by taking the integral of the outer radius minus the inner radius.

Ridiculous

Above is only necessary if there are 2 functions involved. This question involves a single, parametrized curve. The proper course of action here is to eliminate the parameter, find the bounds (which in this case are the points where y=0) then integrate like you would any other single variable function. Good luck!
