$\huge{\fcolorbox{cyan}{pink}{SoluTion:--}}</p><p>$

we know that:

Volume of sphere:-

$\pink {\boxed{ \frac{4}{3} \pi \: {r}^{3} }}$

Given radius :- 2.1 cm

$\implies \frac{4}{3} \times \frac{22}{7} \times 2.1 {}^{3} \\ \\ \implies \frac{4}{3} \times \frac{22}{7} \times 2.1 \times 2.1 \times 2.1 \\ \\ \implies88 \times 0.7 \times 0.3 \times 2.1 \\ \\ \implies \pink{ \boxed{38.908 \: cm {}^{3} }}$

•°• Volume of sphere:- 38.908 cm³
