Txoj Kev: Cov qauv rau kev xam qhov ntsuas ntawm lub kaum sab xis ntawm daim duab peb sab tuaj yeem muab tau raws li r=(P + B - H) / 2 Thiab peb paub tias thaj tsam ntawm ib qho lub voj voog yog PIr2 qhov twg PI=22 / 7 thiab r yog lub vojvoog ntawm lub voj voog. Li no thaj tsam ntawm lub voj voog yuav yog PI((P + B - H) / 2)2
