Anyone know this question?
Hitman42 [59]

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.
