(A) The volume $V$ of a sphere is given by the formula $V = \frac{4}{3} \pi r^{3}$.Given,radius $r = 2.1 \, m$.Substituting the value of $r$ in the formula:$V = \frac{4}{3} 	imes \frac{22}{7} 	imes (2.1)^{3}$$V = \frac{4}{3} 	imes \frac{22}{7} 	imes 2.1 	imes 2.1 	imes 2.1$$V = 4 	imes 22 	imes 0.1 	imes 2.1 	imes 2.1$$V = 88 	imes 0.1 	imes 4.41$$V = 8.8 	imes 4.41 = 38.808 \, m^{3}$.
