Answer:
Step-by-step explanation:as we know that arc length is
s=r*∅
as given angle in degree so convert it in radian we get
angle=2.09 rad
r=3.5 cm
hence we get
s=3.5*2.09 =7.315 cm
perimeter of sector = s +d where d=2*r=2*3.5=7 cm
perimeter of sector=7.315+7=14.315 cm

The semi-circles in the triangles represent the verteces or different angles on certain points of the triangle.

Answer:
the second statement is true
Step-by-step explanation:
Hey there!
12 ≥ 5f - 18
5f - 18 ≤ 12
ADD 18 to BOTH SIDES
5f - 18 + 18 ≤ 12 + 18
SIMPLIFY IT!
5f ≤ 30
DIVIDE 5 to BOTH SIDES
5f/5 ≤ 30/5
SIMPLIFY IT!
f ≤ 6
Therefore, your answer is: f ≤ 6
Good luck on your assignment & enjoy your day!
