Answer:

 π units^2.

Step-by-step explanation:

The area = π r^2   where  r = the radius and the radius = 1/2 * the diameter.

So the radius of this circle = 1/2 * 2 = 1.

The required area =  π * 1^2

= π units^2.

ANSWER

Exact form: π units square.

Or 3.14 square units.

EXPLANATION

The area of a circle is calculated using the formula:

[tex]Area = \pi \times {r}^{2} [/tex]

From the diagram, the diameter of the circle is d=2 units.

The radius is half of the diameter which is 1 unit.

We substitute r =1 into the formula to obtain;

[tex]Area = \pi \times {1}^{2} [/tex]

[tex]Area = \pi \: [/tex]

In decimal form, the area is

[tex]Area =3.14 \: square \: units[/tex]
