ok so i really do not understand what i have to do here and i would love if someone could help me out just a bit:

i have to find the perimeter and volume of a solid.the base od the solid is the region of the xy-lane bounded by: y=x^2 -2x +2 , y=0, x=0, and x=3.

the cross section is a semicircle with diameter in the base of the solid.

does anyone have any idea as to how i should go about doing this?thanks in advance =)
