Answer:
feet, or 14.14 feet
Step-by-step explanation:
Use the arc length formula:
s = rθ
To use the formula, we have to convert the central angle to radians.
90° is equivalent to 
radians, so plug this and the radius into the formula:
s = rθ
s = (9)()
s =
So, the length of the arc is 
feet, or approximately 14.14 feet
they are saying x = 3 so you would use the middle equation
so -4x becomes -4(3)
-4 * 3 =-12
Answer:
y=650
Step-by-step explanation:
First add 25=y/(4+22) to get 25=y/26 then multiply both sides by 26 for y=650
