Pomanga, zozungulira ndizofala kwambiri. Amagwiritsidwa ntchito pazifukwa zosiyanasiyana: mu maziko, mazenera, panthawi yokonza. Chowerengeracho chidzakuthandizani kuwerengera mwachangu dera la bwalo. Kuti muchite izi, lowetsani mfundozo ndikupeza zotsatira.
Muyenera kuyika deta mu mita, ndipo zotsatira zake zimapezeka mu masikweya mita - m². Chowerengera chomwe chikuyembekezeredwa chimawerengera dera ndi radius, chilinganizochi chili motere:
S = p²
Kumene:
- S - malo omwe mukufuna,
- r ndi utali wa bwalo.
Mwa diameter
Ngati mukufuna kuwerengera dera ndi mainchesi, ndiye chowerengera pansipa chidzakuthandizani.
Fomula yowerengera pankhaniyi ndi:
S=π*d2/4
Kuti d ndiye m'mimba mwake mozungulira.
Tiyeni tiwerengere kuchuluka kwa miyala yapaving ya kukula kotchuka 100 * 200, kwa nsanja yozungulira pansi pa brazier ndi m'mimba mwake 6 mita.
Timalowetsa mtengo wa 6 metres mu chowerengera kuti muwerenge kuchuluka kwake ndikupeza - Malo okwana 28,26 sq. Timamasulira masentimita kukhala mita ndikuwerengera malo amiyala yopaka uXNUMXbuXNUMXbone - 0,02 m².
Ikutsalirabe kugawa dera la uXNUMXbuXNUMXbbwalo ndi miyala yoyatsa: 28,26/0,02=1 zidutswa.
Chowerengera chozungulira chidzakuthandizani kuwerengera, ingolowetsani deta yofunikira ndikupeza yankho.
