a solid sphere of radius 10.5 cm is melted and recast into smaller solid cones each of radius 3.5 cm and height 3 cm find the numbers of cone formed​

Answer 1

Question,

a solid sphere of radius 10.5 cm is melted and recast into smaller solid cones each of radius 3.5 cm and height 3 cm find the numbers of cone formed

Given,

radii 1=10.5 cm (r1)

radii 2= 3.5 cm

height= 3 cm

To find,

no. of cones formed.

Answer,

let the volumn of sphere be x and volumn of cone be y.

no of cones ,,,

$\div{volumn of sphere/volumn of cone}$

$\div{4/3 pie r^3/1/3 pie r^2 h}$

$\div{4/3pie10.5^3/1/3 pie 3.5^2 × 3}$

126 cones......
