What is the volume of the cylinder?

V = 17003.1

Step-by-step explanation:

Formula of the volume of a cylinder: V = pi*r^2*h

But in this case it tells you to replace pi with 3.14, so plugging in your numbers into the formula...

V = (3.14)(19)^2*(15)

= 17003.1

Notes: r = 19, because half of 38 is 19

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
