The surface area of a cylinder is 2 \pi rh+2 \pi  r^{2}  because a cylinder is a rectangle when unfolded plus the area of the two circles.

2(3.14)(66)(25)+2(3.14)( 66^{2} )=10,362+27,355.68=37,717.68

So the surface area is 37,717.68 cm^{2}

The volume of a cylinder is  \pi  r^{2} h

(3.14)( 66^{2} )(25)=341,946

So the volume is 341,946 cm^{2}
