points 3. Leaving your answer as an exact answer, find the 10 sin(2 x) volume of the solid generated by rotating the region bounded by f(0) = cos(0), g(0) = sin(20), and 0 = 0 about 0.8 the x-axis. (Even though these two functions will cos(x) 0.6 generate infinitely many such regions, consider only the bounded region represented in the graph.) 04 02 02 0.4 0.6 0.8 (7 points) 4.
