Answer:
Perimeter = 24 + 8π /3 m.
Step-by-step explanation:
Arc length = rC where r = radius and C = angle in radians.
40 degrees = 40 π / 180
= 2π /9 radians.
Arc length = 12 * 2π /9
= 8π /3 m.
Perimeter of the sector = 2*12 + 8π /3
= 24 + 8π /3 m.

Answer:
√180 or 5√6
Step-by-step explanation:
Plug in: a^+b^2=c^2
a^2+12^2=18^2
a^2+144=324
subtract 144 from both sides
a=√180
a= 5√6
true because integers are all positive numbers, their opposites (negatives), and zero
