Lub hom phiaj ntawm kev paub thiab kev nkag siab lub thawv ntawm txoj kab yuav ua kom paub qhov txawv ntawm qhov square, yog li ntawd cov khoom siv tau kom raug thiab tsim nyog thiab muaj txiaj ntsig zoo. Raws li qhov no, yuav pib ua hauj lwm tam sim ntawd, uas yog, kev kawm thiab kev paub txog kev paub txog cov poom hloov, thiaj li paub txoj kev paub no zoo siv tau.
1. Thaum twg yuav muab cov khoom yuav los tau, puas yog qhov tseem ceeb tshaj?
Muab cov khoom tso sib xyaws rau kev xaiv cov khoom tsim nyog los ua txoj haujlwm no tiag, thiab txhua yam yuav tsum tau muab coj los txhawm rau kom muaj kev txiav txim siab thiab kev xaiv kom raug. Cov teeb meem no, vim tias lawv txhua tus muaj feem xyuam nrog kev yuav khoom ntawm cov khoom, yog qhov tseem ceeb xav txog thiab xav tau. Lawv yog cov tib yam tseem ceeb. Yog tsis muaj qhov txawv ntawm lawv. Vim li no, qhov xaus uas yuav twv tau yog yam uas muaj feem xyuam rau cov khoom siv yuav tsis zoo sib xws.
2. Koj puas yuav tsum tau ua qee qhov kev npaj ua ntej yuav yuav ib qho hloov tau?
Ua ntej yuav muab cov poom hloov, yuav tsum tau ua qee yam kev npaj ua haujlwm, thiab nws yuav tsum tau ua tiag tiag thiab nqa tawm vim tias nws yog ib qho tseem ceeb heev. Ntxiv mus, muaj ob lub homphiaj rau kev ua txoj haujlwm no. Ib tug yog kom muaj kev cuam tshuam qhov tseem ceeb ntawm kev yuav khoom ntawm qhov khoom, thiab lwm qhov yog kom tsis txhob xaiv tsis raug. Nyob rau hauv cov ntsiab lus ua haujlwm, muaj ob txoj hauv kev, ib qho yog to taub meej txog qhov chaw siv khoom siv thiab siv cov kev cai, thiab qhov thib ob yog to taub txog qee yam lus qhia txog cov khoom thiab cov chaw tsim khoom, nrog rau cov khoom muag, qhov loj, tsis tau, khoom zoo thiab tus nqi, thiab kev pab cuam tom qab muag ntawm qhov khoom, kev xav tau ntawm cov haujlwm no yog qhov tseem ceeb, yog li yuav tsum zam kev txiav txim tsis raws cai thiab tsis yog.
3. Qhov ntim, qhov hnyav thiab qhov ntim ntawm cov nyiaj them ua ke them li cas?
Qhov muab xam ntawm qhov ntim ntawm qhov hloov yuav muaj feem xyuam rau cov duab ntawm qhov hloov tau. Yog hais tias qhov hloov tau yog ib lub cylinder, nws lub ntim tau tsuas yog suav tias yog thaj chaw hauv qab lossis thaj chaw ntawm lub voj voog ntau zuj zus los ntawm qhov siab ntawm lub tank. Qhov nyhav yog xam los ntawm qhov muab cov ntim ntawm lub thawv hloov los ntawm qhov kev nqus ntawm cov ntaub ntawv siv. Tsis tas li ntawd, yog tias qhov hloov tau hollow thiab qhov hollow feem kuj yog ib tug kheej kheej, qhov ntim ntawm lub cylindrical plhaub yog tag nrho ntim rho tawm qhov hollow ntim, thiab qhov hnyav ntawm lub cylindrical plhaub yog qhov ntim ntawm plhaub cylindrical multiplied los ntawm kev nqus ntawm cov khoom siv. Ntxiv mus, nws cheeb tsam ncig yog lub vojvoog sib cuam tshuam los ntawm lub voos kheej-kheej thiab cov multiplied los ntawm 3.1415926.
Qhov muab xam ntawm qhov ntim ntawm qhov hloov tau yog formula formula, uas yog: ntim = (πR) 2 * h, qhov twg R yog lub vojvoog ntawm thaj chaw hauv qab, h yog qhov siab ntawm qhov hloov tau, nws yuav tsum tau sau tseg tias hauv kev xam Daim phab ntsa qhov yuav tsum tau muab tshem tawm thaum hauv qab lub vojvoog nraub qaum dhau. Txwv tsis pub, qhov kev suav qhov tseeb tsis muaj tseeb.
