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!
The domaine of a functions is the set of the values wherein the function is defined, or the set of the values that the function may take. The range is the image of the function.
Answer A is correct.
C and D are correct too by the definition of the inverse functions.
F is a correct answer.
