Answer 1
Answer:

Answer:

it is not a direct variation

Step-by-step explanation:

To have a direct variation

y/x = k for all values of x and y

y/x = 11/7

y/x    = 13/8

y/x = 15/9 = 5/3

y/x = 17/10

11/7 does not equal 13/8 so  it is not a direct variation

Answer 2
Answer:

Answer:

Not direct variation.

Step-by-step explanation:

To have direct variation, each division of a y value by its corresponding x value must give the same answer.

Look at x = 7, y = 11

Do y/x = 11/7 = 1.5714...

Now look at x = 8, y = 13

Do y/x = 13/8 = 1.625

Since the two divisions do not give equal results, this is not direct variation.

r1² π : r2² π = 9 : 1.44
r1 : r 2 = 3 : 1.2
r2 = 1.2 · r1  / 3
r 2 = 0.4 · r1
If the two cylinders are similar than also: h 2 = 0.4 · h 2
V 1 = r1²   · π  · h1
V 2 = ( 0.4 r1)² π · 0.4 · h1 = 0.064 r1² · π · h1
V 2 ( small cylinder )= 0.064 · V 1 ( large cylinder )
