Question

Help!!!!!!!!!!!!!!!!!!!!

Answer 1

π units^2.

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 2

Exact form: π units square.

Or 3.14 square units.

EXPLANATION

The area of a circle is calculated using the formula:

`Area = \pi * {r}^(2)`

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;

`Area = \pi * {1}^(2)`

`Area = \pi \:`

In decimal form, the area is

`Area =3.14 \: square \: units`
