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 area of the circle:
A=\pi r^2

r - the radius

We have the diameter of the circle: d = 6cm.
d = 2r, therefore

2r = 6cm → r = 3cm

Substitute to the formula:


A=\pi\cdot3^2=9\pi\ cm^2
