To find the area of a circle, you can use the formula A = πr², where A is the area, r is the radius, and π is a constant approximately equal to 3.14.

Step 1: Identify the radius. In this case, the radius is given as 19 millimetres.

Step 2: Substitute the radius into the formula. A = 3.14 * (19 mm)²

Step 3: Calculate the square of the radius. (19 mm)² = 361 mm²

Step 4: Multiply the result by π. A = 3.14 * 361 mm² = 1133.54 mm²

So, the area of the circle is approximately 1133.54 square millimetres, rounded to the nearest hundredth.
