Well diameter will be the diagnol of that square..
let side of square be x, then diagonal will be root2 * x  = diameter
so, raidus will be = dia/ 2
 = (root2 * x ) /2
        
             
        
        
        
Answer:
$23.85
Step-by-step explanation:
39.95 x 3 which can also be 39.95 + 39.95 + 39.95=119.85
So then do 143.70-119.85 to find the answer which is 23.85.
 
        
                    
             
        
        
        
Bryan does indeed have enough money to pay back Jennifer.
We have the 2 numbers -15 and 20. The absolute values of those numbers are 15 and 20.
All we have to do is subtrace 15 from 20. We have the result of positive 5, meaning Bryan will still have $5 left over.
