A = 1.5 π in² ≈ 4.7 in²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 3² × 
= 9π × 
= 1.5π in²
≈ 4.7 in² ( to the nearest tenth )
Answer:
x=0
Step-by-step explanation:
If you combine like terms it is x^2 +6x -27=-27
x^2 +6x =0
x^2=0

Answer:

Step-by-step explanation:
Let's first get the square root of 0.02...
≅ 
Let's convert that to a percentage...
14.14%, which is less than 18%, so it checks out in that sense...
Now, let's convert 0.1414 to a fraction...
, which is greater than
(You can check this by multiplying
by
)
Therefore,
makes the inequality true.
