Answer:
 Interest= $ 18.73
Step-by-step explanation:
Given :  $600 at 9.5% for 120 days
To find : Find the interest due
Solution :
Simple interest formula  
Principle(P)=$600 , rate(r)=9.5%=0.095 , time (t)= 120 days 
In years, 1 year = 365 days 
1 day =  year
 year
120 days =  year
 year
Put values in the formula 
 
 
   
 
Therefore, Interest= $ 18.73

Answer:
The volume is decreasing at a rate 20π cubic meter per hour.
Step-by-step explanation:
We are given the following in the question:
The radius is increasing at a rate 1 meter per hour.
 
                
The height is decreasing at a rate 4 meter per hour   

At an instant time t,
r = 5 meter
h = 8 meters
Volume of cylinder =
 
where r is the radius and h is the height of the cylinder.
Rate of change of volume is given by:

Putting all the values we get,

Thus, the volume is decreasing at a rate 20π cubic meter per hour or 62.8 cubic meter per hour.
