Answer 2

Answer:

I) 1437.33 cm^3

ii) 1.048 m^3

Step-by-step explanation:

$volume \: of \: sphere \: = \: \frac{4}{3} \pi \: r {}^{3} \\ \\ 1.) \: volume \: = \frac{4}{3} \times \frac{22}{7} \times 7 {}^{3} \\ = 1437.33 \: cm {}^{3 } \\ 2.) \: volume \: = \frac{4}{3} \times \frac{22}{7} \times 0.63 {}^{3} \\ = 1.048 \: m {}^{3}$
