Answer:

Step-by-step explanation:Radius of cone   =5cm

Height of cone    =8cm

Radius of sphere=0.5cm

the Volume of the cone is,

=  3 1

​  πr  2  h

=  3 1

​   π×5  2 ×8

=  3 200

​  πcm  3

 

Volume of lead shot =  34

​ πr  3

 

=  3 4

​ π×0.5  3

 

=  6 1

​   πcm  3

 

∴ number of lead shots =  3 200

​  π×  4 1

​  ÷  61

​  π

=  3 50π

​ ×  π 6

​  

=100
