Question

A sphereof radius 12 cm is melted and cons of radius 3 cm and height 4 cm are formed. How many such cones can be formed ?​

Answer 1

102 cones can be formed by 1 sphere

please make me brainlist and don't forget to give thanks

Answer 2

First Find the volume of Cone and Sphere

Volume of Sphere=4/3 π r^3

Given:Radius of Sphere is 12cm

So, replacing the value of Radius we got:

4/3×π×12×12×12=2304π..(1)

Now, Volume of Cone is =1/3 π×r^2 ×h

Radius of Cone=3cm

Height =4cm
Replacing the value we got=1/3×π ×3×3×4

=12π

No, total nos. of Cone is =

=2304×π/12π

=192Cones
