Ịchọta ebe nke okirikiri oyi akwa

N'akwụkwọ a, anyị ga-atụle usoro ndị nwere ike iji gbakọọ elu ebe oyi akwa (iberibe nke a bọl): gburugburu, bases na ngụkọta.

Nkọwa nke oyi akwa okirikiri

Igwe okirikiri (ma ọ bụ iberi bọọlụ) - nke a bụ akụkụ nke fọdụrụ n'etiti ụgbọ elu abụọ yiri ya na-ejikọta ya. Foto dị n'okpuru ebe a na-acha odo odo.

• R bụ radius nke bọọlụ;
• r₁ bụ radius nke mbụ ịkpụ isi;
• r₂ bụ radius nke abụọ ịkpụ isi;
• h bụ elu nke sppherical oyi akwa; perpendicular site na etiti nke mbụ isi ruo n'etiti nke abụọ.

Formula maka ịchọta ebe oyi akwa okirikiri

Spherical elu

Iji chọta ebe dị n'elu okirikiri nke okirikiri, ịkwesịrị ịma radius nke bọọlụ ahụ, yana ịdị elu nke ịkpụ.

S_{Mpaghara mpaghara} = 2 πRh

Ala

Mpaghara nke ntọala nke iberi bọọlụ hà nhata ngwaahịa nke square nke radius kwekọrọ na ọnụọgụgụ. π.

S₁ =r₁²

S₂ =r₂²

Elu zuru oke

Ngụkọta elu elu nke a okirikiri oyi akwa nhata na nchikota nke ebe nke okirikiri elu ya na abụọ bases.

S_{mpaghara zuru oke} = 2πRh + πr₁² +πr₂² = π(2Rh + r₁² +r₂²)

Notes:

• ma ọ bụrụ na kama radii (R, r₁ or r₂) nyere dayameta (d), Ekwesịrị kewaa nke ikpeazụ site na 2 iji chọta ụkpụrụ radius chọrọ.
• uru ọnụọgụgụ π mgbe a na-agbakọ, a na-agbakọta ya na ebe iri abụọ - 3,14.
