Final answer:
The area of the purple region is approximately 13 cm².
Step-by-step explanation:
The diameter of each circle is 2 cm, therefore the radius is 1 cm (half of the diameter). To find the area of a circle, we use the formula A = πr², where A is the area and r is the radius.
So, the area of one circle is A = π(1 cm)² = π cm².
Since there are 4 circles, we multiply the area of one circle by 4: A = 4π cm².
To find the numerical value of the area, we can approximate the value of π to 3.14.
Therefore, the area of the purple region is approximately 4(3.14) cm² = 12.56 cm².
Rounded to the nearest whole number, the answer is 13 cm².
