Step-by-step explanation:

For the big cylinder you multiply the height by each answer and whichever one becomes the height of the small one is your answer.

Hope this helps :)

D, 1/3.

Looking at the picture, you can determine that the smaller cylinder is 1 and 3, while the larger cylinder is 3/9. When trying to solve for the scale factor, or the amount a figure has been increased/decreased by, you have to solve a proportion (for scenarios of this nature, you'd divide).

**When dividing, use the side lenghts for the old and the new.

3                      1           =       1

__         ÷       ___              

9                      3          =       3

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
