Expert Answer:

begin mathsize 12px style Height space of space the space cylinder space is space straight H minus 2 straight R
Total space surface space area
equals surface space area space of space the space sphere plus lateral space surface space area space of space cylinder minus surface
space space space space space area space of space top
equals 4 πR squared plus 2 πr left parenthesis straight H minus 2 straight R right parenthesis minus πr squared end style
