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:
The new mean for the exam scores is 51
Step-by-step explanation:
the mean can be calculated using the formula
mean of scores = 
before the 20 points was added, the mean of the score was = 50.
Inserting this into the formula, we have:
50 = 
from this, we can compute the sum total of the scores as
sum total = 50 × 20 = 1000
when the extra 20 marks is added, the sum of the entire scores will be changed to 1000 + 20 = 1020.
Hence the new mean will be computed as (New Sum total of scores / Number of students)
= 
= 51.
∴ The new mean of the scores is = 51
Answer:
x ={0; - 1 ; 2 ; 1}
Step-by-step explanation:
x¹³-2x¹²-x¹¹+2x¹⁰=0
x¹⁰(x³-2x²-x+2)=0
x¹⁰(x+1)(x-2)(x-1)=0
x¹⁰=0 ∨ x+1=0 ∨ x-2=0 ∨ x-1=0
x=0 x= - 1 x= 2 x= 1
The answer would be rotation
