Remark
If you have the area of the sector, then what you need is the area of the triangle in order to find the area of the shaded area. Just subtract the two.
Area of the triangle
The right angle makes finding the base and height very easy since they are equal
Area_Triangle = 1/2 * b * h
b = 9
h = 9
Area = 1/2 * 9 * 9
Area = 1/2 * 81
Area = 40.5
Area of the Shaded Area
Area_shaded = area of the sector - area of the triangle.
Area_shaded = 20.25 * pi - 40.5
Area_shaded = 20.25(pi - 2) <<<< Answer
Answer:
A, D
Step-by-step explanation:
Sub the x and y values into the equation. The x value is the first number in the coordinate, and the y value is the second number.
If the left side is equal to the right side, it is a solution.
Example:
4x-5y=24
4(-9)-5(-12)=24
-36+60=24
24=24
Remember: if the left side does not equal the right side, it is not a solution.
Answer:
The answers are A and D
Step-by-step explanation:
2/6 simplified is 1/3 and none of the other choices are equal to 1/3, so the answers are A and D.
