Answer: 14.32 units
Step-by-step explanation:
The formula for calculate the distance between two points is:

In this case, given the points (-2,8) and (11,2), we can identify that:

Therefore, we just need to substitute values into the formula in order to calculate the distance between the given points. This is (Rounded to the nearest hundred):

The area ratio is 1:16 meaning that the old area is 1 while the new area is 16. So this is another way of saying "the area is multiplied by 16"
Take the square root of each part of the ratio of 1:16 and we get 1:4
So this is the scale factor. It tells us how the linear components of the circles relate to one another. If the circumference of the smaller circle is 1,then the larger circle has a circumference of 4.
Therefore, the circumference has been multiplied by 4
Answer:
perimeter = 82 inches
Step-by-step explanation:
To find the perimeter, add all of the side lengths together
5*1/5+1/5*15=4
1 + 3 =4
This should equal 4 if I did this correctly.
