Answer 2

Answer:

Explanation:

Cylinder:

h=20 cm

r=1.5 cm

Sphere:

r=1.5 cm

Number of spheres · Volume of sphere=Volume of cylinder

n ·  (4/3)πr^3=πr^2h

n= πr^2h    

    (4/3)πr^3

π gets canceled.

n=r^2h      

    (4/3)r^3

n=1.5·1.5·20        

    (4/3)·1.5·1.5·1.5

The 2 1.5 gets canceled. 

n=20       

   (4/3)·1.5

n=10

Therefore 10 spheres can be made.
