Answer:
16π square centimeters.
Step-by-step explanation:
The area of a circle is πr².
Here, we are given the diameter, but we just need to divide it by 2 to get the radius.
8/2 = 4
So, the radius is 4 cm.
Now, we can substitute it into the formula to find the area.
π x 4²
π x 16
16π
So, the area of this circle is 16π.
