Final answer:
The area of the circle with a radius of 6mm is 113.04mm².
Step-by-step explanation:
The diameter of a circle is equal to twice the radius, so if the radius is 6mm, the diameter would be 12mm.
Since the area of a circle is calculated using the formula A = πr², we can substitute the radius value of 6mm into the formula to find the area.
So, the area of the circle would be A = π(6mm)².
To find the missing measurement, we can use the value of π as 3.14. Therefore, A = 3.14(6mm)² = 3.14(36mm²) = 113.04mm².
