The circumference of a circle is always calculated by 2

R
So if R=2.5 m this circumference is 2*

*2.5 m
Which is 5

m (choice B)
Hope this helped!
Start with the second expression. That factors easily into (8x-3)(8x+3).
Since 64x^2 + 48x + 9 has no negative signs, I'd bet that the common factor is (8x+3). Divide <span>64x^2 + 48x + 9 by that to verify.

Hello!
First, let's write the problem.

Let's switch sides now, otherwise, we are going to end up doing it later.

Multiply both sides by 54.5.

We could also rewrite that as,

Simplify.



That would be our final answer, we could round it to.
x ≈ 3.40
