Rectangle WXYZ with height h and width w is rotated 360° about segment WY. Which choice gives the solid formed and its surface area?

Rectangle, A = 2 • w • h square units
Rectangle, A = w • h square units
Cylinder, A = 2π • w • h + 2π • w2 square units
Cylinder, A = π • w • h + π • w2 square units

Name each raycalculation tip: in ray "ab", a is the endpoint of the ray.
