Answer:
25,132.74 miles
Step-by-step explanation:
Hello!
We are basically asked to find the circumference of the Earth's cross-section.
Circumference: 
We can replace 2r with the diameter, because the diameter is 2 times the radius.
Multiply the Diameter by pi:
It is around 25,132.74 miles around.
Your gonna have to put the options in the question
Answer:
A. Translation
Step-by-step explanation:
Given
Preimage



Image



Required
Which transformation occurred
The transformation that occurs is translation because each of the preimage were translated or shifter right by 8 units.
The rule applied here is:

So, we have:


<em>Hence, the transformation is (a) Translation</em>
