(1) The region bounded by the given curves is rotated about y = 9.

x=(y-10)^2 , x=1.

Find the volume V of the resulting solid by any method.

and

(2) The region bounded by the given curves is rotated about the y-axis.

y=-x^2+15x-54, y=0.

Find the volume V of the resulting solid by any method.

I got (2*pi)/5 for number 1 and (135*pi)/2 for second one, dunno if it is correct.
