(D) Given,radius $(r) = 7 \, cm$.The formula for the volume of a sphere is $V = \frac{4}{3} \pi r^3$.Substituting the given values:$V = \frac{4}{3} 	imes \frac{22}{7} 	imes (7)^3 \, cm^3$$V = \frac{4}{3} 	imes \frac{22}{7} 	imes 7 	imes 7 	imes 7 \, cm^3$$V = \frac{4 	imes 22 	imes 7 	imes 7}{3} \, cm^3$$V = \frac{4312}{3} \, cm^3$Converting the improper fraction to a mixed fraction:$V = 1437 \frac{1}{3} \, cm^3$.Thus,the required volume is $1437 \frac{1}{3} \, cm^3$.
