Maths Quiz: Tafuta eneo lililotiwa kivuli

[pincode]

4th yr, engineering Udsm. The solution: The shaded area = total area- area of quarter circle= ((1/2x BCx AB) + (IIx AC^2)/2) - IIx AC^2/4 = 8872.9 sqrcm- 1385.4sqrcm= 7487.5 sqrcm

kaka naona unachanganya kanuni;nusu duara eneo ni hiyo kweli??no offence plz try again much respect km nimepotea nielekeze

 

[Kurzweil]

How did you your answer?

Kuna neno umelisahau? Au sentensi iko kama ilivyo?

 

[mwanamabadiliko]

Nimesharekebsha AC should be divided by 2 to get the radius, ur right,

then 1715 sq cm limeisha hili wa ukenyenge una jingine???

kama ni mhandisi tutegemee ajali kibao kutoka kwako hesabu ya darasa la sita muhula wa kwanza

toa jibu usiwe km jina lako aisee hizo approx tu;na kuwekeana cv wengine hatuna kbs@jungu weka jawabu mwache eng

You can actually use any approach, sema JF haina option ya kuweka integral symbol na option za kuandika equations!! MODs, tusaidieni kutuwekea hizi symbols za integral na equations watu wajimwage siyo siasa tu!

Nasikia Ritz kapita hapa akielekea chitchat.vp umeshamuona mkigoma mitaa hii.

Vijana swali simple sana hii!!
1)Eneo la triangle ABC
½×56×42=1176cm²
2)Eneo la semicircle AC
½×Π×r²
r=AB/2
By Pythagoras theorem
AB=70cm
r=70/2=35cm
:-area=½×Π×35²=1825cm²
3)Eneo la Robo duara BC
¼×Π×42²=1386cm²

Turudi kwenye swari sasa
SHADED AREA=(Eneo la triangle ABC+Eneo la semicircle AC)-(Eneo la robo duara BC)
=>Numerically
Required area
=[(1176+1925)-1386]cm²
=(3101-1386)cm²
=1715cm²
:-The shaded area is 1715cm²

Unasema uko mwaka wa nne Uhandisi, Chuo Kikuu DSM? Janga la taifa!

Umejuaje hiyo pembetatu ina angle yenye nyuzi tisini? Na umejuaje hapo kuna nusu duara? No wonder tunahitaji wachina mpaka kutusaidia kujenga vivuko vya mito.

Swali halijibiki.

 

[WA-UKENYENGE]

Hivi:[(Πx(BA-BC)x(BA+BC))+(4xBCxBA)]/8 where Π=3.1415926536, BA=56cm and BC=42cm

Wakuu! Assumptions ni mhimu kuweka, Mfano: The triangle ABC is not stated to be a right, however most of the attempters are babtizing the triangle ABC to be the right angled!!

Mkuu swali linajibika, you just have to make some intelligent assumptions!

Mkuu, triangle ABC is not stated to be right angled, you should change your approach instead of pythagoras theorem! May be try integration method (Like numerical methods) or the sine and cosine rules!!

 

[WA-UKENYENGE]

then 1715 sq cm limeisha hili wa ukenyenge una jingine???

Mmmmhhh mbona hujasema umelipataje? Harafu naona watu mnaliona vibaya hilo lipembe tatu (Je ni kweli hiyo pembe tatu ni pembe tatu mraba? na kama jibu ni ndiyo, kwa vigezo gani?)!! Pia nusu duara naona watu wanaibatiza tu! kama ni nusu duara muonyeshe logics za kuiita nusu duara!!

 

[WA-UKENYENGE]

Kuna neno umelisahau? Au sentensi iko kama ilivyo?

Yeah, nilisahau neno mkuu! My appologise for any inconviences!! Nilimaanisha How did you get your answer?

Hapana mkuu, tunaanzia kwenye umbo kama hilo then we finally come up with structure like this!!
