diketahui volume bola 288 π cm kubik tentukan diameter

Dik. Volume bola = 288 phi cm^3
Dit. diameter bola?

Jawab...

Volume bola = 4/3 × phi × r^3
@ 288 × phi = 4/3 × phi × r^3 (Coret phi)
@ 288 × 3/4 = r^3
@ 216 = r^3
@ r = 6cm > diameter = 2r = 2(6) = 12cm

Semoga membantu.. ^_^

volume bola = 4/3.phi. r^3
4/3.phi.r^3 = 288 phi cm^3
4/3.r^3 = 288 cm^3
r^3 = 216 cm^3
r = 6 cm^3. Jadi diameter = 2.r = 2.6 = 12 cm
