Summad (Pi)

Pi ama madoorsoome lagu xisaabo wareega goobo (${\displaystyle {\pi }}$) Sidoo kale waa astaan loo isticmaalo badanaa Fisigis ${\displaystyle {\pi }}$ Xarafka yer ee gariiga ayaa laga soo qaatayPi.

Waa xaraf kamid ah kuwa gariiga

Waxaana loo yaqaanaa xiriiriyaha Gooboiyo Dhexroorkeeda Dhexroor Si jajab ahna looma qori karo, ama xitaa aljebra ahaan ${\displaystyle a/b}$ halkii ${\displaystyle a,b}$ oo ah tiro togan Waxaana loo yaqaanaa Madoorsoomehii Archimedes .

Dhaxroorka =1, wareega waxa uu noqonayaa = π.

Waxaana loo qoraa ${\displaystyle 3.14}$ ama ${\displaystyle 22/7}$.

Tusaale

Cm	(O) Wareega	(d) Dhaxroorka	O/d Wareega / dhaxroorka
Bir canjeero	96.2	29.8	3.22819
Bakeeri	18.4	5.7	3.22807
Xaarin	104.6	32.4	3.2284
Baaf	156.2	48.1	3.2474

Hadaba mar walba oo lagu celcelyo alaaba kala duwan waxaa soo baxaysa tiradaas sidaas daraaeed waxaa lagu hehsiiyey Tiradas laga dhigo 3.14 way raaci kartaa tiro kale sida 3.140012 Laakiin waxaa lagu gaabiyey 3.14, iyadoo sidaas ah ayaa hadana tiradaas waxaa loo sii qoraa (${\displaystyle {\pi }}$) sumadaas.

Joomitiriya

π Joomitiriyada iyo cabirkeeda sida loogu cabiro.

	Habka Joomitiriyada	Qaabka
Goobo	Wareega Goobada waxaa lagu helaa Gacan r iyo Dhexroor d	${\displaystyle O=\pi d=2\pi r\,\!}$
	Bed Waxaa lagu helaa gacanka r	${\displaystyle A=\pi r^{2}\,\!}$
Qabaal	Bed keeda Waxaa lagu helaa a iyo b	${\displaystyle A=\pi ab\,\!}$
Kubad	Mug Waxaa lagu helaa r iyo dhexroor d	${\displaystyle V={\frac {4}{3}}\pi r^{3}={\frac {1}{6}}\pi d^{3}\,\!}$
	Bed waxaa lagu helaa r	${\displaystyle A=4\pi r^{2}\,\!}$
Dhululubo	Dhulubo Mug Waxaa lagu helaa h iyo Gacan r	${\displaystyle V=\pi r^{2}h\,\!}$
	Bedkana h iyo gacan r	${\displaystyle A=2(\pi r^{2})+(2\pi r)h=2\pi r(r+h)\,\!}$
Toobin	Mug Toobin waxaa lagu helaa h iyo Gacan r	${\displaystyle V={\frac {1}{3}}\pi r^{2}h\,\!}$
	Bedkana h iyo gacan r	${\displaystyle A=\pi r{\sqrt {r^{2}+h^{2}}}+\pi r^{2}=\pi r(r+{\sqrt {r^{2}+h^{2}}})\,\!}$
