Question

A solid sphere of diameter 18 cm is melted
and is recast into small identical cones of
height 6 cm and radius of 6 cm. The
number of cones formed is​

Answer 1

Solution:-

Diameter of sphere = 28 cm

Then, radius of sphere = 28/2 = 14 cm

volume of the sphere = 4/3πr³

= 4/3*22/7*14*14*14

Volume of sphere = 11498.66 cu cm

Diameter of cone = 14/3 cm

So, radius of cone = 14/3 ÷ 2

radius of cone = 7/3

Volume of the cone = 1/3πr²h

= 1/3*22/7*7/3*7/3*3

Volume of cone = 17.11

Number of cones formed = 11498.66/17.11

= 672 cones
