Answer:
27
Step-by-step explanation:
vol. of sphere=nxvol. of cones
then n=vol.of sphere/vol.cones
4/3πr^3/1/3πr^2h
36π/4/3π
=27
therefore 27 cones are required

Given:
radius of cone = 2 cm
height of cone = 1 cm
radius of sphere = 3 cm
To Find:
How many solid cones of radius 2 cm and height 1cm can be made from a solid sphere of lead of radius 3cm by melting
Solution:
The volume of sphere=n x volume of cones
Then,
n=
n =
n = 36×
n= 27
Therefore, 27 cones are required
