Answer:
15.6 ft²
Step-by-step explanation:
Given:
Radius (r) of circle = 5.7 ft
m<CBD = 55°
Required: Area of the shaded sector
SOLUTION:
Area of shaded sector = θ/360*πr²
Where,
θ = 55°
π = 3.14
r = 5.7 ft
Plug in your values
Area of shaded sector to nearest tenth = 15.6 ft²

Hopefully it helps you get it right!
Answer:
C is correct
Step-by-step explanation:
If you plug in the ordered pairs from C, they always work.
The answer is 6.
4 quarters is 1 dollar right?
and if you add 2 more, it will be $1.50
This is the easiest way to memorize how to multiply using the number 25.
The slope can be worked out by the equation:
So with the coordinates (1,2) and (-2,4):
x1 = 1 y1= 2 and
x2 = -2 y2 =4
Note that x1 and y1 use the same coordinate, vice versa with x2 and y2.
Tip: The equation can be y1-y2 and x1-y2 too (have a think why)
So the answer is 2/-3, which is the same as C)
-2/3
