We can use this formula: C = 2 * $\pi$ * r
We can't use the diameter in this formula. We have to use the radius. And the radius is half of the diameter.

9 / 2 = 4.5

And we'll also use 3.14 for [tex] \pi [/text].

Plug in all the values:

C = 2 * 3.14 * 4.5
C = <span>28.26

So, the circumference is 28.26.</span>

dsp73

Answer:

The correct option is commutative property.

Step-by-step explanation:

The expression that Renee is simplifying is:

$(7)\cdot(\frac{13}{29})\cdot(\frac{1}{7})$

It is provided that, Renee recognizes that 7 and $\frac{1}{7}$ are reciprocals, so she would like to find their product before she multiplies by $\frac{13}{29}$ .
