Question

Cones 3cm high and 3.5cm radius are made by melting a sphere of 10.5cm radius. find number of cones.
​

Answer 1

Solution:

Volume of sphere = 4/3r

= 4/3*22/7*10.5*10.5*10.5

Volume of metallic sphere = 4851 cm

Now, Volume of one cone = 1/35r2h = 1/3*22/7*3.5*3.5*3

Volume of one cone = 38.5 cm

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 Answer.
