Volume bola dengan diameter 42cm adalah​

Dik :

D = 42 cm

r = 42/2 = 21 cm

Dit :

Volume bola = ?

Peny :

Volume bola

V = 4/3 × π × r³

V = 4/3 × 22/7 × 21³

V = 4/3 × 22/7 × 9.261

V = 4/3 × 22 × 1.323

V = 4 × 22 × 441

V = 88 × 441

V = 38.808 cm³

Sekian dan terima kasih

PENYELESAIAN:

 frac{4}{3} pi {r}^{3} = \ frac{4}{3} times frac{22}{7} times 21 times 21 times 21 = \ 4 times 22 times 21 times 21 = \ 88 times 441 = \ 38808 : {cm}^{3}
