Shigar da radiyo ko tsayin diamita don ƙididdige ƙarar yanki.

Ƙirar ƙididdiga

Wannan kalkuleta ne wanda ke ƙididdige ƙarar sephere ko ball, ma'auni na tallafi da raka'a na sarauta (inci, ƙafafu, yadudduka, mm, cm ko mita), kuma sakamakon ƙara zai iya canzawa zuwa naúrar daban-daban, tare da dabarar lissafi da tsayayyen gani. Sphere, yana taimaka mana mu sami amsoshi da fahimtar sakamako cikin sauƙi.

Yadda ake amfani da wannan kalkuleta?

  1. Zaɓi don amfani da diamita ko radius don ƙididdige ƙarar.
  2. Shigar da tsayin diamita ko radius
  3. Karɓi shigarwar ƙididdiga ko juzu'i, misali. 3.4, 1.7, 5 1/4 ko 3/5
  4. Zaɓi sashin diamita ko radius
  5. Zaɓi naúrar ƙarar da kuke son sani
  6. Za ta lissafta sakamakon ta atomatik kuma ta amsa tare.
  7. Sakamakon lissafin za a zagaye.

Yadda za a lissafta ƙarar yanki?

Sphere wani abu ne mai kamala zagaye na geometric mai girma uku, tare da kowane maki akan samansa yayi daidai da tsakiyarsa. Yawancin abubuwan da aka saba amfani da su kamar ƙwallaye ko globes su ne sassa. Idan kana so ka ƙididdige girman yanki, sai kawai ka nemo radius ɗinsa ka toshe shi cikin tsari mai sauƙi,
V = 4⁄3πr³.

Tsarin Juzu'i na Sphere

Ƙididdigar girman yanki shine sau 4/3 pi sau radius cubed. Cubing lamba yana nufin ninka shi da kansa sau uku, a wannan yanayin, radius yana ninka radius.

V = 4⁄3πr³
Girman Sphere = 4⁄3 × π × radius × radius × radius
πshine rabon da'irar da'irar zuwa diamita

Misalin lissafi

Nemo ƙarar yanki mai radius inci 4.

Girma = 4⁄3π4³
4 ÷ 3 × 3.141592653589793 × 4 × 4 × 4 = 268.082573106329.
Bayan zagaye, girman shine 268.08 cubic inci.

Idan muna son musanya raka'a na ƙara zuwa raka'a daban-daban, za mu iya musanya raka'o'in radius zuwa guda ɗaya da farko.
misali,
Sphere tare da radius na inci 9.
Menene girma a ft³?

radius 9 in = 9 ÷ 12 ft = 0.75 ft girma = 4⁄3π0.75³
4 ÷ 3 × 3.141592653589793 × 0.75 × 0.75 × 0.75 = 1.7671458676442584
bayan zagaye, ƙarar shine ƙafar cubic 1.77.

Idan kawai muna da adadin diamita, rabin diamita shine radius, kawai raba diamita ta 2, kuma za mu sami radius.
