V = PI x r^2 x H
1348.79 = 3.14 x 5.5^2 x H
1348.79 = 94.985 x h
h = 1348.79 / 94.985
h = 14.2 cm  ( round answer if needed)

Answer:
length and width = 40 and 10 ft.
Step-by-step explanation:
The perimeter of a rectangular toddler play area is 100 feet.
Perimeter = 2(length + width)
Let the width = w
The length is 10 feet more than 3 times the width. Length = 10+(3w)
now put the values
100 = 2(10+3w + w)
100 = 2w + 20 + 6w
100 = (2w + 6w) + 20
100 = 8w + 20
8w = 100 - 20
w =  
 
w = 10 feet.
Now Length = 10+ (3w) 
                      = 10+( 3 × 10)
                      = 10 + 30
                      = 40 feet
Therefore, length = 40 feet and width = 10 feet
 
        
             
        
        
        
-100 is rational.
-100 can be turned into a fraction by doing the following...
Just put 1 underneath -100 and you get 
So that means it is rational since it can be a fraction!
