AB = DC = 4cm

AD = CB = 2cm

**peter**, Sunday, January 9, 2011 at 5:01amThe real problem is that I do not comprehend the question.

The part I'm really stumbling over is the "rotated about the side AB". I have no idea what that means..

I have another question that is quite similar...so if anyone can explain, it would be greatly appreciated.

**drwls**, Sunday, January 9, 2011 at 6:20amWhat you get when you perform the indicated rotation of the rectangle about side AB is a cylinder with radius = 2 cm and length h = 4 cm. The line AB is the axis of the cylinder.

The volume is

V = pi*r^2*h = 16*pi cm^3

Do the calculation.
