1.	If h, S and V denote respectively the height, curved surface area and volume of a right circular cone, then 3πVh3 - S2h2 + 9V2 is equal to(a) 8(b) 0(c) 4π(d) 32π2
Answer» If h, S and V denote respectively the height, curved surface area and volume of a right circular cone, then $3 {πVh}^{3} - S^{2} h^{2} + 9 V^{2}$ is equal to (a) 8 (b) 0 (c) 4 $π$ (d) 32 $π^{2}$
