The area of a circle is calculated using the formula $A = \pi r^2$, where $r$ is the radius of the circle. Given the diameter is 8.6 inches, the radius is half of that, which is 4.3 inches. Substituting the values into the formula gives $A = 3.14 \times (4.3)^2 = 3.14 \times 18.49 = 58.0596$ in.$^2$, which rounds to 58.06 in.$^2$.
