(A) The surface area of a sphere is given by the formula $S = 4\pi r^{2}$.Given $S = 1256 \, cm^{2}$ and $\pi = 3.14$.$1256 = 4 	imes 3.14 	imes r^{2}$$1256 = 12.56 	imes r^{2}$$r^{2} = \frac{1256}{12.56} = 100$$r = 10 \, cm$.The volume of a sphere is given by $V = \frac{4}{3} \pi r^{3}$.$V = \frac{4}{3} 	imes 3.14 	imes (10)^{3}$$V = \frac{4}{3} 	imes 3.14 	imes 1000$$V = \frac{12560}{3} = 4186 \frac{2}{3} \, cm^{3}$.
