The general equation for computing the circumference of a circle is 
, where C is the circumference, and d is the diameter. (You might also see the equation as 
where r is the radius, because 
)
Computing the circumferences of the two circles, we get:
.
To calculate the ratio of two numbers, we can divide one by the other. You can look at this as "How many times does the denominator fit in the numerator?"
So the circumference of the complex impact crater is 2 times greater than the circumference of the simple impact crater.

Step-by-step explanation:
Given
Solving (a):
We have:
Express f(x) as y
Swap x and y
Add 8 to
Square both sides
Rewrite as:
Express y as:
To determine the domain, we have:
The original function is
The range of this is:
The of the
function is the
