The answer is the third one
-the hours are unknown so its 6+4h
the total is 130 and she earns an extra 20 dollars so
(6+4)h+20=130
Answer:
Maybe 180° -50° = 130°
So I think x= 130°
Step-by-step explanation:
My opinion though
V=pi*r^2*h*1/3
12pi=pi*r^2*4/3
R needs to be equal to 3 to be squared into 9 to make the equation true.
So the radius is 3 inches.
I hope this helps!
