Answer:
Pi or 3.14 units squared.

The formula for finding the area of the circle is pi times the radius squared. The radius is half of the diameter, so half of 2 is 1. Then plug 1 back to the formula. 1 to the power of 2 is 1 times pi is pi. Therefore, the area of this circle is 3.14 or pi units squared. Hope this helps!
