Answer:
According to this description the area [tex]A[/tex] of the disc is:
[tex]1650in^{2}<A<1700in^{2}[/tex]
On the other hand, the area of a circumference is given by the following equation:
[tex]A=\pi r^{2}[/tex] (1)
Where [tex]r[/tex] is the radius.
If we want to know the possible lengths of [tex]r[/tex] for the circular disc, we will have to apply equation (1) for both areas:
For [tex]A=1650in^{2}[/tex]:
[tex]1650in^{2}=3.14 r^{2}[/tex]
[tex]r=\sqrt{\frac{1650in^{2}}{3.14}}[/tex]
[tex]r=22.91 inches[/tex]
For [tex]A=1700in^{2}[/tex]:
[tex]1700in^{2}=3.14 r^{2}[/tex]
[tex]r=\sqrt{\frac{1700in^{2}}{3.14}}[/tex]
[tex]r=23.26 inches[/tex]
Therefore the radius could be 22.91 inches or 23.26 inches
