^^^^^^^^

I’m pretty sure the speed was decreasing (if we’re talking about the same question). The question stated that the material was being processed at a rate of 100 tons per hour, and the rate of raw material going in at the time given was less than 100, so that means the total amount of tons was decreasing.

And jatt… the answer was pi(integral, from 0 to 2) ((1-f(x))^2-(1-g(x))^2)dx
Hope that helps!
