Step-by-step explanation:
 
8x + 6) - (x + 4)
8x + 6 - (x + 4) 
8x + 6 - x - 4 
7x + 2
 
 
        
             
        
        
        
It is 6cm
Because a hexagon has 6 sides and if each side is 1cm long then add 6 to 1

Answer:
V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =  πr³ ( r is the radius )
 πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V =  × 3.14 × 9.3³
 × 3.14 × 9.3³
    =  × 3.14 × 804.357
 × 3.14 × 804.357
    = 
    ≈ 3367.6 cm³ ( to the nearest tenth )
