Answer:
12. 524 in³ (3 sig. fig.)   13. 2000 cm³ (3 sig. fig.)
Step-by-step explanation:
12. Volume of sphere = (4/3)πr³ 
= 500/3π
= 524 in³ (3 sig. fig.)
13. Volume of cylinder = πr²h
= 7²π(13)
= 637π
= 2000 cm³ (3 sig. fig.)
 
        
             
        
        
        
20 + 20 + 30 + 15 + 40 = 125
125/5= 25
25-15 = 10
Absolute deviation for 15 is 10
        
                    
             
        
        
        
Answer:
5z+30
Step-by-step explanation:
5(z+6) 
^ multiply each term in the parentheses by 5
5z+5x6
then,
5z+5x6 (multiply the numbers)
the answer will be 5z+30
