Find the area of the shaded regions:

18 pi cm^2

18 (3.14) =56.52 cm^2

or use the pi button 56.54866776 cm^2

Step-by-step explanation:

First find the area of the entire circle

A = pi r^2

A = pi 9^2

A = 81 pi

The area of a circle is 360 degrees.  The shaded area is 80 degrees

Take the fraction of the circle that is shaded and multiply by the total area

80/360 * 81 pi

2/9 * 81 pi

18 pi

We can approximate pi

18 (3.14) =56.52

or use the pi button

56.54866776

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
