Step-by-step explanation:
is similar to
so we can write the ratio

Solving for x, we get

Answer:
C=84
Step-by-step explanation:
Since you use 3 for pi. You plug the radius into the formula. C=2×3x14=84
Answer:
i do think it's D or C
Step-by-step explanation:
D or C
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 answer to this question is D: 2. To solve this, you must work backwards, and what's the oppsite of addition? Subtraction! Take 2.34, your final answer, and subtract .34 from it, and you end up with 2! I hope this helped! Could I possible get brainliest?
