Area of the quarter sector
Area of the entire circle = pi * r^2
Area of the quarter circle = pi r^2 / 4
r = 9
Area of the quarter circle = pi 9^2 / 4
Area of the quarter circle = pi 81/4 = 20.25 pi
Area of the triangle
Area pf the triangle = 1/2 b*h
b = h = r
r = 9
Area of the triangle = 1/2 9 * 9
Area of teh triangle = 1/2 81
Area of the triangle = 40.5
Area of the shaded area
The shaded area = Area of the 1/4 circle - area of the triangle
The shaded area = (20.24 pi - 40.5)ft^2
A <<<<<< Answer.
Answer:
y = - 3x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (3, - 5) ← 2 ordered pairs from table
m = 
= 
= - 3, thus
y = - 3x + c ← is the partial equation
To find c use any ordered pair from the table
Using (3, - 5 ), then
- 5 = - 9 + c ⇒ c = - 5 + 9 = 4
y = - 3x + 4 ← equation of line
V=πr^2h
V= volume, r=radius, and h=height
Plug in what you know.
1,728= 3.14*r^2*22
Combine like terms.
1,728= 69.08*r^2
Divide both sides by 69.08.
25. 0144759.... Round down to 25.
25=r^2
The square root of 25.
r=5
The radius is about 5 centimeters.
I hope this helps!

Step-by-step explanation:
the coordinates of the midpoint are the mean value between the coordinates.
M = ((-6 + 0)/2, (4 + -8)/2) = (-6/2, -4/2) = (-3, -2)
