Volume of Cylinder
= πr²h 
= (3.14)(5)²(16)
= 1256 cm³ 
Volume of Cone 
= 1/3πr²h
= 1/3(3.14)(4)²(12) 
= 200.96 cm³
Volume of air space 
= Volume of Cylinder - Volume of Cone
= 1256 - 200.96 
= 1055.04 cm³ 
≈ 1055 cm³ (nearest whole number)
        
                    
             
        
        
        
Answer:
-17 =s
Step-by-step explanation:
-8s +4 = -7s +21
Add 8s to each side
-8s+8s +4 = -7s+8s +21
4 = s+21
Subtract 21 from each side
4-21 = s+21-21
-17 =s
