Answer» Volume of sphere = 4/3πr³= 4/3*22/7*10.5*10.5*10.5Volume of metallic sphere = 4851 cm³Now,Volume of one cone = 1/3πr²h= 1/3*22/7*3.5*3.5*3Volume of one cone = 38.5 cm³Total number of cones = Volume of metallic sphere/volume of one cone= 4851/38.5= 126 conesTotal number of cones that can be formed is 126 |
