Question

A metallic sphere of radius 10.5 cm is melted and then recast into small cone each of radius 3.5cm and height 3cm,the number of suck cone is

Answer 1

Answer:

Step-by-step explanation:

Volume of sphere=2/3πr^3

=2/3×22/7×10.5×10.5×10.5

=2425.5cm cube

Volume of cone=1/3πr^2h

=1/3×22/7×3.5×3.5×3

= 38.5cm cube

No. Of cones = volume of cube/volumes of cone

= 2425.5/38.5

= 63 cones
