Find the volume obtained by rotating the following curves bounded by:
y=sinx y=0 pi/2≤ x ≤ pi

Best ResponseYou've already chosen the best response.0Cylindrical gave me : ∫(pi/2 to pi) 2pi (x) sinxdx but integration by part didn't give me the right answer and the answer key gave me ∫pi(x)^2 dx which I don't understand from where it comes from.
