Answer:
h =  - r
 - r
Step-by-step explanation:
The question requires you to make h the subject of the formula. 
S = 2πrh + 2πr²
subtract 2πr² on both sides.
S - 2πr² = 2πrh - 2πr² -  2πr² 
S - 2πr² = 2πrh
Dividing both sides by  2πr
(S -  2πr²)/2πr =  2πrh/ 2πr
h =  - r
 - r
 
        
                    
             
        
        
        
Answer:
125%
Step-by-step explanation:
1. Set up the equation 
425/340 = x/100
(percentages are out of 100 so this equation means 425 out of 340 is equal to a number out of 100) 
2. Cross multiply 
340x = 42500
3. Solve for x 
x = 125
 
        
                    
             
        
        
        
3 consecutive means 
x, x+1, x+2
OR
x, x-1, x-2
the equation based on givens and first equation is:
2(x) + 2(x+1) = 69 - (x+2)
4x + 2 = 67 - x
5x = 65
x = 13
so the largest would be x+2 or 15
