By definition, the volume of the cone is given by:
 V = (1/3) (π) (r ^ 2) (h)
 Substituting values we have:
 V = (1/3) (π) ((4/2) ^ 2) (5)
 V = (20/3) (π)
 Then, the volume of the cylinder is:
 Vc = 3 * V
 Vc = 3 * (20/3) (π)
 Vc = 20π
 Answer:
 
the volume of the original cylinder jesse bought is:
 
Vc = 20π

                  3*2=6

16/6 is equivalent to 8/3

Writing a proportion:-

Sonja [21]
2/10 represents 20 percent, as 10 is 100% because it is the Max, so something like 4/10 would be considered 40%
