Answer:
9pi
Step-by-step explanation:
circumference= 2 (pi) (r)
radius = diameter \ 2
r = 9 \ 2 = 4.5in.
c = 2 (pi) (4.5)
c = 9pi or 28.3in.
Hope this helps!

The <em><u>correct answer</u></em> is:
C.4.1 in
Explanation:
We will use a proportion for this problem.
In the first ratio, we have 6 inches: 80 pounds. This can also be written as 6/80.
For the second ratio, we do not know the length; this is x. The weight is 55; this gives us x/55.
This makes our proportion
6/80 = x/55
Cross multiplying, we have
6(55) = 80(x)
330 = 80x
Divide both sides by 80:
330/80 = 80x/80
4.125 = x
This means the answer is 4.1.
Grace’s because she followed the order of operations. Addition and subtraction first, then multiply and divide.
Answer:
-n+1
Step-by-step explanation:
h(n)-g(n) =n+2-2n-1 ,collect like terms
n-2n+2-1 = -n+1
