jari-jari setengah bola =5 cm tentukan volume benda

Vol.O
= 4/3 pi r^3
= 4/3 (3,14)(5 cm)^3
= 4,186 * 125 cm^3
= 523,25 cm^3
————————— :2
= 261.625 cm^3

Dik: r = 5 cm
Dit : [tex] v_{1/2 bola} [/tex] =?
Jawab: v=4/3 [tex] \pi [/tex] [tex] r^{3} [/tex]
             [tex] v_{1/2 bola} [/tex] = 4/3 . 3,14 .  [tex] 5^{3} [/tex] x 1/2
                                                  = 4/3 . 3,14 . 125 x 1/2
                                                  =12,56/3 x 52,5
                                                  =659,4 x 1/3
                                                  =219,8  [tex] cm^{3} [/tex]
Maaf klo ada yang salah
