R = radius of cylinder and sphere
H = height of cylinder
A = 2PiRH + 2PiR^2
H = height of cylinder
A = 2PiRH + 2PiR^2

Formula has three parts because this is an enclosed structure - the area of the hemisphere, the area of the cylinder, and the area of the circular bottom of the cylinder.
Therefore:
A = 2PiR^2 + 2PiRH + PiR^2
Therefore:
A = 2PiR^2 + 2PiRH + PiR^2
