Question 1: Please solve and select the correct graph.

Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the given curves about the y-axis. y=3/_, y=0, x=1 : Find its circumference c and height h. c( X) = h ( x) = Use shells to find the volume V of S. V =\fLet S be the solid obtained by rotating the region shown in the figure about the yaxis. (Assume a = 8 and b = 4.) y = a sinwx') \fFactor the polynomial and use the factored form to find the zeros. (Enter your answers as a comma-separated list. Enter all answers including repetitions.) P(x) = x3 + x2 + 12x
