Hello there!
Let's consider. What would be the formula that we would use?
The formula that we would use for (area) would be the following:
[tex] \left[\begin{array}{ccc}(r= \sqrt{ \frac{A}{ \pi }) } \end {array}\right] [/tex]
[tex]\boxed{r=7=154/ \pi } = \boxed{\boxed{154}}[/tex]
Your radius would be [tex](7)[/tex].
I hope this helps you!
