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 of the ice-hockey puck is 3.4 inches, the radius is half of that, which is 1.7 inches. Substituting the values into the formula gives $A = 3.14 \times (1.7)^2 = 3.14 \times 2.89 = 9.0746$ square inches.
