Karibu tena — imekuwa muda! Tuendelee pale tulipokomea.

Formula ya eneo la jumla la silinda ni:

A=2πr2+2πrhA = 2\pi r^2 + 2\pi rh

ambapo:

  • AA ni eneo la jumla
  • π\pi ni mara kwa mara (takriban 3.14159)
  • rr ni radius ya msingi wa silinda
  • hh ni urefu wa silinda

Eneo hili linajumuisha eneo la pande mbili za duara (msingi na juu) na eneo la upande wa mviringo.
