Answer:
The perimeter of the kitchen wall = 60 b
Step-by-step explanation:
The number if tiles used in the length side of the square walk = 5 tiles
The length of 1 tiles  = 3 b
So, the length of 5 tiles = 5 x ( Length of 1 tile)  
= 5 x (3 b)  =  15 b
So, the length of the square walk = 1 5 b
Perimeter of SQUARE  = 4 x SIDES
⇒ Perimeter of the wall  = 4 x (Side) 
                                         = 4 x (15 b)  = 60 b
Hence, the perimeter of the kitchen wall = 60 b
 
        
             
        
        
        
Probably, the formula of Volume for a cone of height 'h' and base area 'b' is :
 
 
        
        
        
The circumference of every circle is   (pi) times (diameter).
The diameter is (2 x radius), so we can write
                  Circumference = (pi) x (2 x radius) .
The question gives us the circumference, and the number to use for (pi).
I shall now pluggum in:
                  (31.4 cm)  =  (3.14) x (2 x radius)
Divide each side by  3.14:       (31.4 cm)/(3.14)  =  2 x radius
Divide each side by 2 :            (31.4 cm) / (2 x 3.14)  =  radius
                                                             5 cm  =  radius
