1. 452.16 square centimeters

2. 150.72 square centimeters

3. 25.12 centimeters

Step-by-step explanation:

1. the area of the circle

The area of a circle can be calculated with:

The area of the given circle then, is:

or just 452.16 square centimeters.

2. the area of the minor sector

There's a convenient formula for this, but I don't remember it and you don't really need it. A full circle is 360°, and 120° is exactly 1 third of that. 1 third of the size means 1 third of the area:

or 150.72 square centimeters

3. the area of the minor arc

You can do the same thing here. The circumference of a circle is:

So the circumference of the given circle is:

or about 75.36 centimeters.

One third of that:

25.12 centimeters.
