Answer:
radius is diameter over two
Step-by-step explanation:
so 16 divided by two will be 8
 
        
             
        
        
        
You need do like 25$--------100% of real price
                         x$---------70%
25x70=100<u>x</u>
1,750=100<u>x</u>
    <u> x</u>=1750<u />divided by 100=17.5$
        
                    
             
        
        
        
Squaring both sides of the given equation:  w^2=7w, or w^2-7w=0.  
w^2-7w=0 can be factored:  w(w-7)=0.  Then, w=7 or w=0.  Both 0 and 7 are solutions of this equation.
