what is the area of a circular region whose diameter is 6 centimeters?\n\na $6\\pi$ cm\nb $9\\pi$ cm\nc $12\\pi$ square cm\nd $9\\pi$ square cm
Answer
Explanation:
Step1: Identify the radius from diameter
$$r = \frac{d}{2} = \frac{6\text{ cm}}{2} = 3\text{ cm}$$
Step2: Apply the circle area formula
$$A = \pi r^2$$
Step3: Calculate the final area
$$A = \pi (3\text{ cm})^2 = 9\pi \text{ square cm}$$
Answer:
D. $9\pi$ square cm
