Answer:
120 cm. .here u go..
Step-by-step explanation:
Circumference: 2πr
C=18 so r= 18/2π= 9π
Arc length = rθ 6=(9π)θ θ=6/9π
Convert to degrees by multiplying by 180/π
6/9π x 180/π = 120 degrees
Hope it helps!

Answer:
r<=-8 or r is less than or equal 8
Step-by-step explanation:
-2r+3>=19
-2r>=16
r<=-8
you flip the sign when the variable is a negative. To plot this on a number line place a close circle on -8 moving to the left direction.

Answer:
m∠z = 106°
Step-by-step explanation:
From the figure attached,
By exterior angle theorem,
m∠z = a + 68°
By linear pair theorem,
m∠a + 142° = 180°
m∠a = 180° - 142°
= 38°
Therefore, m∠z = 38° + 68°
= 106°
