<h3><u>Answer:</u></h3>
  • r = 2.82
<h3><u>Step-by-step explanation:</u></h3>

<u>Given: </u>

  • A = 25

<u>Let's simplify.</u>

  • => 25 = \frac{22}{7} r^{2}
  • => \frac{25}{\frac{22}{7} } = \frac{\frac{22}{7}r^{2}  }{\frac{22}{7\\} }
  • => \frac{7(25)}{22} = r^{2}
  • => \sqrt{\frac{25(7)}{22}}= \sqrt{r^{2}}
  • => \sqrt{\frac{25(7)}{22}}= r
  • => r = 2.82 (Estimated)

<u>Therefore, r ≈ 2.82.</u>

Hoped this helped.

First you multiply 44.94 and .07 (the decimal equivalent of 7%) which gives you 3.1458. You take 3.1458 and add it to 44.94 (since it's an additional fee) and that gives you 48.0858
