Answer 2

Answer:

Area = 51.7 square inch

Step-by-step explanation:

      $circumference = 2 \pi r\\\\25.5 = 2 \pi r\\\\r = \frac{25.5}{2 \pi }\\\\Area = \pi r^2$

              $= \pi ( \frac{25.5}{2 \pi})^2\\\\= \pi \times \frac{650.25}{4 \pi^2}\\\\= \frac{650.25}{4 \pi}\\\\=\frac{162.5625}{\pi}\\\\= 51.7 \ in^2$
