Is this correct? Q: Use the method of cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis. xy = 7, x = 0, y = 7, y = 9 A: \(\huge\int\limits_7^9 (2 \pi)(y)(\frac{y}{7}) dy = \frac{772 \pi}{21}\)
Omg... and 28\(\pi\) is the answer, correct. Ty much @TuringTest I can't believe I made such an easy error >_<
stupid algebra, I still don't like it much either :/
