To solve, set an equation:
First Number: x
Second Number: 2x
x+2x=36
3x=36
divide both sides by 3
x=13
First Number: (x) 12
Second Number: (2x) 24
Answers: 12 and 24
        
                    
             
        
        
        
Answer:
72
Step-by-step explanation:
C = pi* d 
pi= 3 (given in the problem)
d=24(the diameter is given in the picture)
C= 3*24 = 72

Answer:
   B)  43.82 feet/sec
Step-by-step explanation:
Fill in the number and evaluate:
   v = √(64×30) = √1920 ≈ 43.82 . . . . ft/s
_____
Of course, √(64h) can be simplified to 8√h. You know that √30 lies between 5 and 6, so the velocity lies between 8·5 = 40 and 8·6 = 48. There is only one answer choice in that range.
