Answer:
The answer is (π/4)*r
Step-by-step explanation:
Formula length of arc when the angle given is in radian as the case given
s = r*θ
s = arc length (in radians)
r = radius
θ = central angle in radians
But when the angle given is in degrees the length is expressed as
s= 2πr*(θ/360)

Type that out please I can't read it sideways
2.5
5x+3x=20
8x=20
x=20/8=2.5
-4v + 8 > -3v - 9
-v + 8 > -9
-v > -17
v < 17
is negative, it doesn't have any real roots.
