(A) Given:Radius of the cone $(r) = 3.5 \, cm = \frac{35}{10} \, cm = \frac{7}{2} \, cm$.Height of the cone $(h) = 12 \, cm$.The formula for the volume of a right circular cone is $V = \frac{1}{3} \pi r^2 h$.Substituting the values:$V = \frac{1}{3} 	imes \frac{22}{7} 	imes (3.5)^2 	imes 12$$V = \frac{1}{3} 	imes \frac{22}{7} 	imes \frac{7}{2} 	imes \frac{7}{2} 	imes 12$$V = \frac{1}{3} 	imes 22 	imes \frac{1}{2} 	imes 7 	imes 6$$V = 11 	imes 14 = 154 \, cm^3$.Thus,the volume of the cone is $154 \, cm^3$.
