Calculate Circle Area: Now, we use the formula for the area of a circle, which is $A = \pi * r^2$ . $A = 3.14 * (19 \, \text{cm})^2$ $A = 3.14 * 361 \, \text{cm}^2$ $A = 1133.14 \, \text{cm}^2$ We round this to the nearest hundredth.
Apply Formula: After rounding, the area of the circle is approximately $1133.14$ square centimeters.
