(i)Given radius, r = 6 cm
Height, h = 7 cm
Volume of the cone = (1/3)r2h
=(1/3)×(22/7)×62×7
= 22×12
= 264 cm3
Hence the volume of the cone is 264 cm3.
(ii) Given radius, r = 3.5 cm
Height, h = 12 cm
Volume of the cone = (1/3)r2h
=(1/3)×(22/7)×3.52×12
= (22/7)×12.25×4
= 154 cm3
Hence the volume of the cone is 154 cm3.
