Dit : V bola ?
Jawab : 4 . 22/7 . r.r.r / 3
= 4 . 22/7 . 42..42.42
= (4 x 22) . ( 42 : 7) . 42.42
= 88 x 6 x 1764
= 528 x 1764
= 931.392 / 3
= 310.464
2. Dik: luas.bola : 1256
Dit : volum bola ?
jawab : L.bola = 4 x 3,14 x r x r
= 12,56 .r.r = 1256
= r.r = 1256 / 12,56
r.r = 100
r = 10
V.bola = 4. 3,14 . r.r.r / 3
= 12,56 . 10 .10 .10 / 3
= 12,56 . 1000 / 3
=12560 / 3
= 4186,6
