Good morning :

1. Determine the volume of objects obtained by rotating the area bounded by the curve y = x2 and y = 2 x2 against the xaxis 2. Determine the volume of objects obtained by rotating the area bounded by the curve x = y2 + 1 and y = x 1 against the y axis 3. Specify the length of the fix} curve from point P to Q for the following functions : 1 7' 109 3 a. x):x?+E with Pll'E] and (2%,?) b. f(x)=(x2+1)m with {1%} and Q[4,2'17m] 3 3
