Maformula ekuverenga radius yebhora (sphere)
Mashoko ari pasi apa anoshanda chete kune . Chimiro chekutsvaga radius chinoenderana nerudzi rwechimiro, funga zvakajairika sarudzo.
Regular triangular piramidhi
Pamufananidzo:
- a - kumucheto kwechigadziko chepiramidhi, kureva zvikamu zvakaenzana AB, AC и BC;
- DE - kureba kwepiramidhi (h).
Kana kukosha kwehuwandu uhu huchizivikanwa, saka tsvaga radius (r) bhora rakanyorwa/sphere rinogona kupihwa neformula:
Chinhu chakakosha chepiramidhi yenguva dzose yetriangular ndiyo yakarurama. Kwaari, fomula yekuwana radius ndeiyi inotevera:
Regular quadrangular piramidhi
Pamufananidzo:
- a - kumucheto kwechigadziko chepiramidhi, kureva AB, BC, CD и AD;
- EF - kureba kwepiramidhi (h).
nharaunda (r) bhora rakanyorwa/sphere rinoverengwa sezvizvi:
Regular hexagonal piramidhi
Pamufananidzo:
- a - kumucheto kwechigadziko chepiramidhi, kureva AB, BC, CD, DE, EF, YE;
- GL - kureba kwepiramidhi (h).
nharaunda (r) bhora rakanyorwa/sphere rinoverengerwa neformula:
