Answer:
Hey There!
Let's solve....
Radius=5cm
Angle = pi/3
Therefore arc length= Radius×angle

The arc length is 5.23 cm when Theta=pi/ 3 and radius is 5 cm.

Answer:
A: 144 cm
B: 64 cm
C: 36 cm
Step-by-step explanation:
The volume of a cone is given by ...
V = (1/3)πr²h
Solving for h, we get ...
3V/(πr²) = h
Filling in the given values, we get ...
3(192π)/(πr²) = h
576/r² = h
Then the heights of the different cones are ...
A: r = 2, h = 576/4 = 144 . . . cm
B: r = 3, h = 576/9 = 64 . . . cm
C: r = 4, h = 576/16 = 36 . . . cm
Answer:

Step-by-step explanation:
In this problem we have a regular octagonal barrier (That means that all the length side are equal)
Find out the perimeter of the barrier
The perimeter is equal to

where
b is the length side of the barrier
we have

substitute in the formula of perimeter

Convert to mixed number
