ditanya: volum bola?
di jawab: Vb=4/3 πr³
=4/3.3,14.5.5.5
=4/3.3,14.125
=4/3.392,5
=1570/3
=523,33 cm³
b)dik: r=4,2 dm
dit: volum bola?
dij: Vb= 4/3πr³
=4/3. 22/7.4,2.4,2.4,2
=4/3.22.0,6.4,2.4,2
=4/3.13,2.4,2.4,2
=4.4,4.4,2.4,2
=310,464 dm³
c) dik: d=12 cm, r =12:2=6
r =6 cm
dit: volum bola?
dij: Vb=4/3πr³
=4/3.3,14.6.6.6
=4.3,14.2.6.6
=904.32 cm³
