Let's start with the area of a circle formula: A = pi * r^2, where r is the radius. The radius is half the diameter. Since the diameter here is 6, the radius is 3. Now we can start solving! 1) A = pi* (3^2) 2) A = 9pi The area in terms of pi is 9pi cm^2. I got 9pi cm^2, but it is always helpful to double check work. Hope this helps!
