Answer: 18
Step-by-step explanation:
The circumference formula is C= 2
r
r being the radius, so you can just plug in.
C= 2
(9) = 18
The answer is A.
Reasoning:
Choice B says to subtract 1/5. However since 1/5 has a variable next to it, it would need to be divided not subtracted
Answer:
<em>s= </em>-5.57 (rounded to the nearest hundredth)
Step-by-step explanation:
1. Multiply s and 2 by 7.
You'll get -7s-14. We'll come back to this later
2. Subtract 12 from 37.
You'll get 25
3. Add 14 to both sides so that you cancel out the -14.
The equation stands as -7s= 39
4. Divide both sides by -7 so that we leave <em>s </em>by itself.
s= -5.57142857
