The formula to calculate the circumference of a circle is C=2πr, where r is the radius of the circle and π (pi) is a constant approximately equal to 3.14.

Given that the radius of the cutter is 19 millimeters, we can calculate its circumference as follows:

C = 2πr

C = 2 x 3.14 x 19

C = 119.32

Therefore, the cutter's circumference is approximately 119.32 millimeters

Answer: The circumference of the cutter is approximately 119.32 millimeters.

Step-by-step explanation: The formula for the circumference of a circle is C=2πr, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

In this problem, the radius of the circular cutter is given as 19 millimeters, so we can substitute that value into the formula:

C = 2πr

C = 2 × 3.14 × 19

C = 119.32

Rounding to the nearest hundredth, we get:

C ≈ 119.32 millimeters

Therefore, the circumference of the cutter is approximately 119.32 millimeters.
