Volume of sphere = 4/3πr³
= 4/3*22/7*10.5*10.5*10.5
Volume of metallic sphere = 4851 cm³
Now,
Volume of one cone = 1/3πr²h
= 1/3*22/7*3.5*3.5*3
Volume of one cone = 38.5 cm³
Total number of cones = Volume of metallic sphere/volume of one cone
= 4851/38.5
= 126 cones
Total number of cones can be formed is 126
