I only know #1 which is 0.85
        
                    
             
        
        
        
The radius is half of the diameter so if the diameter is 3 then the radius is 1.5. ANSWER:1.5 what I did was just divide 3by 2 to get half of 3.

Write a recursive and explicit formula for each option.
Save a nickel on the first day of the month and then double the amount each day for a month
=> a1 =0.05
=> a2 = a1* 2 = 0.05*2 
=> a3 = a2*2 = a1* 2*2
..............................................
=>recursive an =  
 
=> explicit an = 0.05* 
 
Start their savings by saving  $10  on the first day and then  $10  each day of the month
=> a1 = 10 
=> a2 = a1 + 10 = 20
=> a3 = a2 +10 = 20 +10 =30 
........................................................
=> recursive an = 
=> explicit an = 10 + 10( n-1)
