Answer:
4 cm
Step-by-step explanation:
Perimeter = 18cm
θ = 2.5 radian
s = rθ, s = Arc length
Perimeter of Sector, P = arc length, s + 2r
Perimeter = rθ + 2r
r = Radius
18cm = r(2.5) + 2r
18cm = 2.5r + 2r
18cm = 4.5r
r = 18 /4.5
r = 4
Answer:
7x - 5y = -5 this is the standard form
I think A which is 4in but not sure
We can re-group them to add more easily.
300 + 400 = 700
42 + 16 = 58
700+58 = 758
