Answer:
The answer to your question is: h = 14.5 in
Step-by-step explanation:
Data
radius = 5 in
Volume = 725 π in³
height = ?
Formula
                Volume = 2πr²h
            
Substitution
                      725 π in³ = 2πr² h
                     h = 725π / 2πr²
                     h = 725 / 2(5)²
                     h = 725 / 50
                     h = 14.5 in
 
        
             
        
        
        
No area is shown. So befoe sam divided it, 
the area of tge original rectangle was . . .
     8 x 0  =  zero .
        
             
        
        
        
H=45d h stands for hours and 45d means 45 minutes per day
