(i)Given radius, r = 6 cmHeight, h = 7 cmVolume of the cone = (1/3)r^{2}h=(1/3)×(22/7)×6^{2}×7= 22×12= 264 cm^{3}Hence the volume of the cone is 264 cm^{3}.(ii) Given radius, r = 3.5 cmHeight, h = 12 cmVolume of the cone = (1/3)r^{2}h=(1/3)×(22/7)×3.5^{2}×12= (22/7)×12.25×4= 154 cm^{3}Hence the volume of the cone is 154 cm^{3}.
