ok I showed my work.. I used this formula integral Pı(outer r)^2-Pı(inner)^2 inside integral from y=0 to y=1 pi(1-y)^2 - pi(1-y^2)^2 my result is 7/6 pi..:( where am I wrong??

volume of solid:( hi..I tried to solve it but ı couldn't .book says the answer is pi /6...please help me. question is; y=x and y=x^1/2 about y =1

thanks,yu are a good man :smile:

thanks.. one more guestion that I can't solve is...lim 1-sinX/cosx =? X->pi/2 (I don't like trigonometric questions in limit) thanks:)

:!) lim(1-x).tan Pi X/2=? x->1 please help meee :!)
