» Jawa :

$\tt volume = \frac{4}{3} \times \pi \times {r}^{3}$

$\tt = \frac{4}{3} \times \frac{22}{7} \times {28}^{3}$

$\tt = \frac{4}{3} \times \frac{22}{7} \times (28 \times 28 \times 28)$

$\tt = \frac{4}{3} \times \frac{22}{ \cancel7} \times 28 \times 28 \times \cancel{28} {}^{4}$

$\tt = \frac{4}{3} \times 22 \times 28 \times 28 \times 4$

$\tt = \frac{4 \: \times \: 22 \: \times \: 28 \: \times \: 28 \: \times \: 4}{3}$

$\tt = \frac{88 \: \times \: 28 \: \times \: 28 \: \times \: 4}{3}$

$\tt = \frac{2.464 \: \times \: 28 \: \times \: 4}{3}$

$\tt = \frac{68.992 \: \times \: 4}{3}$

$\tt = \frac{275.968}{3}$

$\tt = > {91.989,33 \:} = > {91.989,33 \: \: cm}^{3}$
