Answer:

  • [tex]r = 2.82[/tex]

Step-by-step explanation:

Given:

  • [tex]A = 25[/tex]

Let's simplify.

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

Therefore, r ≈ 2.82.

Hoped this helped.
