Question

A solid metallic sphere of radius 10.5 cm is melted amd recast into a number of smaller cones each of radius 3.5cm and height 3cm .. Find the number of cones so formed

Answer 1

Answer:

Step-by-step explanation:

n=number of cones

4/3*π*10.5*10.5*10.5=4/3*π*3.5*3.5*3.5 * n

n=10.5*10.5*10.5/3.5*3.5*3.5

= 27

number of cones =27
