Looking at the image, we can see that the diameter of the circle is 16 inches.
Since the radius measures half the diameter, so the radius of this circle is equal to 8 inches.
So the missing value in the area formula is 8.
Then, calculating the area, we have:
[tex]\begin{gathered} A=\pi\cdot8^2 \\ A=3\cdot64 \\ A=192\text{ in}^2 \end{gathered}[/tex]
The circle area is equal to 192 in².
Since the question first asks only for the missing value in the formula, so the
