Answer:
2.33 units
Step-by-step explanation:

We know that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (<span>Triangle Inequality Theorem)
so
inequality 1
</span>

<span>
inequality 2
</span>

<span>
the answer is
</span>

<span>
</span>
<span>It's easy enough. Solving looks like that: p(roll of 8)+p(roll of 12) =</span>

Hope everything is clear.
Remember,

, where

is circumference and tex]d[/tex] is the diameter. They are related by a constant

(pi).
We can solve the above equation for d and then substitute our known values.

16 - 2(2w + 1) = 8w - 2(8+w)
16 - 4w - 2 = 8w - 16 - 2w
- 4w + 14 = 6w - 16
14 = 10w - 16
30 = 10w
/10 /10
3 = w
I think so lol
