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 = ${\frac {gP}{2}}=\pi rP$

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

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

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

Mugga

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

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