In order to prove this, you simply plug in the number 2 everywhere you see X:
4^(2) = 8(2).
Simplify
16 = 16 √
Since this checks out, x is proven to be 2.
8.992254284692088 is the radius I believe
If you're asking how much she made per hour, it would be 8.5$
<span>0.888 = 888 / 1000
hope that helps</span>
