I would like them all solved correctly.

Question 11 Not yet Find the volume of the solid obtained when the region under the curve f (x) = x from x = 0 to x = 2 is rotated about the x- answered axis. Marked out of Volume = 1.00 Flag questionQuestion 5 Evaluate the following integral using the method of partial fractions: Not yet answered 3 dx = Marked out of x3 + 5x 1.00 Flag questionQuestion 1 Not yet answered Marked out of 1.00 F Flag question Evaluate the following integral: /( l x2 2 (x + 4)2 )dx=:1 Question 12 Not yet answered Marked out of 100 V Flag question Find the volume of the solid obtained when the region under the curvef(x) = cos(x) from x = 0 to x = the xaxis. Hint: You will find the following double angle formula useful: cos2 (x) = l l E + Ecosax) % is rotated about
