Quis ( 10/10 )A ball has a radius of 7 cm, what is its volume ?

Sebuah bola memiliki radius 7, berapa volumenya?

$:$

V bola = 4/3 × π × r³

→ 4/3 × 22/7 × 7³

→ 4/3 × 22/7 × 343

→ 4/3 × 22 × 49

→ 4/3 × 1.078

→ 4.312/3

→ 1.437,33 cm³

$blue{boxed{pink{boxed{orange{star ~ green{mathcal{S}ilvie ~ mathcal{R}ubia} ~ star}}}}}$

Diket :

Jari – jari bola : 7 cm

Ditanya :

Volumenya :…??

Jawab :

$boxed{ sf : rumus = > v = frac{4}{3} times pi times {r}^{3}}$

_________________________________

$sf : v = frac{4}{3} times pi times {r}^{3}$

$sf = frac{4}{3} times frac{22}{7} times {7}^{3}$

$sf = frac{4}{3} times frac{22}{7} times 343$

$sf = frac{4 : times : 22 : times : 343}{3 : times : 7}$

$sf = frac{30.184}{21} = > 30.184 div 21$

$sf = 1.437,33 : {cm}^{ 3}$

Kesimpulan :

Volume bola tersebut adalah 1.437,33 Cm³ ✅
