Answer:
B. 171.74 cm²
Step-by-step explanation:
Area of a sector =
.
Where,

radius (r) = 8.7 cm
Plug in the values into the formula
Area of sector = 
Area of sector = 
Area of sector = 171.74 cm² (approximated)
I think it’s C but don’t go for my word bc I could be wrong but I rlly think it C for some reason
Answer:
y = 3x - 31
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 )
here m = 3, thus
y = 3x + c ← is the partial equation
To find c substitute (9, - 4) into the partial equation
- 4 = 27 + c ⇒ c = - 4 - 27 = - 31
y = 3x - 31 ← equation in slope- intercept form
