Question

a solid metallic sphere of diameter 28cm is melted and recast into a number of smaller cones each of diameter 4 2 by 3 cm and height 3 cm find the number of counts of almond so formed​

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
