Okuqukethwe
Kulolu shicilelo, sizocubungula ifomula ongabala ngayo umthamo womkhakha we-sphere, kanye nesibonelo sokuxazulula inkinga ukuze ubonise ukusetshenziswa kwayo ngokusebenza.
Ukunqunywa komkhakha webhola
Umkhakha webhola (noma umkhakha webhola) ingxenye ehlanganisa ingxenye eyindilinga kanye nekhoni, i-apex yayo emaphakathi nebhola, futhi isisekelo siyisisekelo sengxenye ehambisanayo. Emfanekisweni ongezansi, umkhakha ufakwe umbala osawolintshi.
- R iyiradiyasi yebhola;
- r iyiradiyasi yengxenye nesisekelo sekhoni;
- h - ubude besigaba; perpendicular ukusuka maphakathi nesisekelo sesegimenti ukuya ephuzwini eliyindilinga.
Ifomula yokuthola umthamo womkhakha we-sphere
Ukuze uthole umthamo womkhakha oyindilinga, kuyadingeka ukwazi i-radius ye-sphere nokuphakama kwengxenye ehambisanayo.
amanothi:
- uma esikhundleni se-radius yebhola (R) kunikezwe ububanzi bayo (d), lesi sakamuva kufanele sihlukaniswe kabili ukuze kutholwe irediyasi edingekayo.
- π ukuzungeza kulingana no-3,14.
Isibonelo senkinga
Indilinga ene-radius engu-12 cm inikezwa. Thola umthamo womkhakha oyindilinga uma ukuphakama kwengxenye equkethe lo mkhakha kungu-3 cm.
Isixazululo
Sisebenzisa ifomula okukhulunywe ngayo ngenhla, sifaka kuyo amanani aziwa ngaphansi kwemibandela yenkinga:
