Toobin

Toobin Waa joomateri ay masaaxad saleedkiisu goobo tahay, masaaxada isku xirta salalkuna tahay Toobin

Qaacidadaan waa Toobinta usamaysan Salkeeda sida Goobada

r : Gacanka Salka.

h : Joogga Toobinta.

A : Bedka Salka.

P : Wareega salka.

V : Mugga Toobinta.

g : Dheerer garaaf toobineed ee gooba quman ah.

Bedka

Bedka dusha sare ee toobin Goobeed quman = ${\displaystyle {\frac {gP}{2}}=\pi rP}$

Bedka salka toobinta = ${\displaystyle \pi r^{2}\,}$

Toobin goobeed quman haddii la gooyo ee barbarra la noqda waxaa ka dhalanaya : ${\displaystyle {\frac {a}{A}}={\frac {k^{2}}{h^{2}}}}$

Halka (a) Waa bedka gabalka la jaray, iyo (k) Fogaanta halka laga jaray madaxa.

Mugga

Mugga ${\displaystyle V}$ Jooga toobin ${\displaystyle h}$ Gacanka Salka ${\displaystyle r}$ iyo ${\displaystyle {1 \over 3}}$ Mugga dhulubo. Sidaas daraadeed:

${\displaystyle V={\pi \cdot r^{2}\cdot h \over 3}}$
