Answer 1

9π in. ²

Explanation:

The circumference of a circle is diameter times pi.

To find the area of a circle, you multiply the radius by itself, and the product by pi.

Diameter (6 in.) divided by two equals the radius (3 in.).

3 x 3 = 9 in.²

Then multiply by pi to get, 9π in.²

Hope this helps! :)

Answer 2

For this case we have that by definition, the circumference of a circle is given by:

`C = \pi * d`

Where:

d: It is the diameter of the circle

We have as data that:

`C = 6 \pi`

So:

`6 \pi = \pi * d`

Thus, the diameter of the circle is 6, therefore the radius is 3.

The area of a circle is given by:

`A = \pi * r ^ 2`

Where:

r: It is the radius of the circle

`A = \pi * 3 ^ 2\\A = 9 \pi`
