Answer:

Volume of a basketball=
$\sf 5600cm^3$

Radius

${\boxed {\sf Volume=\frac {4}{3}\pi r^3 }}$

$\qquad{:}\longrightarrow$
$\sf \frac {4}{3}* \frac {22}{7}* r^3=5600$

$\qquad{:}\longrightarrow$
$\sf \frac {88}{21}r^3=5600$

$\qquad{:}\longrightarrow$
$\sf r^3=5600* \frac {21}{88}$

$\qquad{:}\longrightarrow$
$\sf r^3=\frac {5600×21}{88}$

$\qquad{:}\longrightarrow$
$\sf r^3=(117600)/(88)$

$\qquad{:}\longrightarrow$
$\sf r^3=1336.36$

$\qquad{:}\longrightarrow$
$\sf r=\sqrt [3]{1336.33}$

$\qquad{:}\longrightarrow$
$\sf r=11.01$

$\qquad{:}\longrightarrow$
$\sf r=11cm (Approx)$

$\therefore\sf radius \:of \;basketball\:is\:11cm.$
