Answer:
The ratio of the measure of central angle PQR to the measure of the entire circle is 1/8
The area of the shaded sector depends on the length of the radius.
The area of the shaded sector depends on the area of the circle.
Step-by-step explanation:
1,4,5 on edg
30 sides
To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
7,747
9,021-1,274=7,747
