Answer:

79 square inches

Step-by-step explanation:

First, let's find the diameter given the circumference.

  • [tex]C=\pi d[/tex]
  • [tex]d=\frac{C}{\pi }[/tex]
  • [tex]d= 31.4/3.14[/tex]
  • [tex]d=10[/tex]

Next, we know the the radius is half the diameter, so the radius is 5 inches. Now, we can solve the area of the circle.

  • [tex]3.14 * 5^2[/tex]
  • [tex]3.14 * 25[/tex]
  • [tex]78.5[/tex]
  • 78.5 ≈ 79 square inches

Therefore, the answer is 79 square inches.
