The dere gburugburu a na-akpọ mgbe ọ na-emetụta ihe nile n'akụkụ nke polygon. Tụlee a atụ ole na ole.

Usoro 1: R = S / (P / 2) ebe - S ma R - n'ógbè na perimeta nke ọgụgụ karị.

Formula 2: R = (P / 2 - A) * tg (a / 2), ebe P - perimeta A - ogologo nke onye nke ọzọ, na-na - na-abụghị n'akụkụ nke a nke n'akuku.

Olee otú ịchọta okirikiri nke gburugburu, ma ọ bụrụ na ọ na-ede a nri triangle

Usoro 1:

Okirikiri nke gburugburu nke e dere na rhomb

A gburugburu nwere ike ede ọ bụla rhombus bụ equilateral na scalene.

Usoro 1: R = 2 * H, ebe H - elu nke geometric udi.

Formula 2: R = S / (A * 2), ebe S - bụ nke ebe rhombus, na A - n'akụkụ nke ogologo ya.

Formula 3: R = √ ((S mmehie A) / 4), ebe S - bụ nke ebe rhombus, na A nmehie - enweghị nnukwu n'akuku nke geometrical ọgụgụ.

Formula 4: R = V * T / (√ (V² + G²) ebe B na T - bụ ogologo nke diagonals nke geometrical ọgụgụ.

Formula 5: R = B mmehie (A / 2), ebe - na diagonal nke rhombus, na A - bụ n'akuku na vertices na jikọọ diagonal.

Okirikiri nke gburugburu nke e dere na triangle

Ke edinam na na nsogbu ị na-nyere ogologo nke n'akụkụ nke ọnụ ọgụgụ, mbụ gbakọọ perimeta nke triangle (U), na mgbe ahụ na ọkara perimeta (n):

P = A + B + C, ebe A, B, - na ogologo n'akụkụ nke geometric ọgụgụ.

n = n / 2.

Usoro 1: R = √ ((p-A) * (n-D) * (n-B) / n).

Ma ọ bụrụ na, ebe ọ maara ihe niile nke otu atọ ọzọ, e nyere gị ihe na ebe nke ọnụ ọgụgụ, i nwere ike gbakọọ chọrọ nso dị ka ndị a.

Formula 2: R = S 2 (A + B + C)

Formula 3: R = S / f = S / (A + B + C) / 2), ebe - n - bụ semiperimeter geometric ọgụgụ.

Formula 4: R = (n - k) * tg (A / 2), ebe n - bụ semiperimeter triangle A - onye nke ya n'akụkụ, na tg (A / 2) - tangent ọkara n'akụkụ nke a nke na-abụghị n'akuku.

A n'okpuru n'elu usoro ga-ahụ na okirikiri nke gburugburu nke na-ede ihe equilateral triangle.

Formula 5: R = A * √3 / 6.

Okirikiri nke gburugburu nke e dere na a nri triangle

Ọ bụrụ na a nsogbu nyere ogologo nke ụkwụ na hypotenuse, mgbe ahụ, na okirikiri nke e dere gburugburu dị ka a ghọtara.

Usoro 1: R = (A + B-C) / 2, ebe A na B - ụkwụ, C - hypotenuse.

Na ikpe, ma ọ bụrụ na ị bụ nanị abụọ ụkwụ, ọ bụ oge na-echeta Pythagorean Theorem ịchọta hypotenuse na-eji n'elu usoro.

C = √ (A² + B²).

Okirikiri nke gburugburu na e dere na a square

Gburugburu nke e dere na a square, abahade ya niile 4 n'akụkụ kpọmkwem ọkara isi nke tangency.

Usoro 1: R = A / 2, ebe A - n'akụkụ ogologo nke a square.

Formula 2: R = S / (P / 2), ebe S na F - n'ógbè na perimeta nke a square, karị.
