Answer:
The distance between B to B' is 5
Step-by-step explanation:
Using the distance lie formula:
Let's say (x2, y2) is (-2,1) and (x1, y1) is (1,5)

The distance between the original and new coordinates would be the same, therefore the two will remain a distance of 5.
Answer: 0.8
Step-by-step explanation:
Answer:
Diameter 16, radius 7, circumference 37.68, diameter 8
Step-by-step explanation:
Largest area will be in a circle with the largest radius. So let's find all radii.
d = 8, so r = 4;
r = 7;
circumference = 2pi*r = 37. 68, so r = 6
diameter 18, so r = 8
Between A and B = 12 is A.
