$Given \: : \: Curved \: surface \: area \: of \: a \: sphere \:  = \: 1256 cm ^{2} \\ \\ We \: know \: that, \: Curved \: surface \: area \: of \: a \: spehre =4πr ^{2} \\ \\ ⟹ \: 1256 = 4 \times 3.14 \times {r}^{2} \\ \\ ⟹ \: {r}^{2} = \frac{1256}{4 \times 3.14} \\ \\ ⟹ \: {r}^{2} = 100 \\ \\ ⟹ \: r = 10 \: cm \\ \\ ∴ \: Hence, \: the \: answer \: is  \: 10 cm.</p><p>$
