Answer:
The Formula is 4 x Pi x Radius Squared . surface area of sphere = 4 x pi x radius x radius where "x" indicates multiplication and pi = approximately 3.141592654 4 * pi * r^2
Step-by-step explanation:
 
        
             
        
        
        
58 * 1,000 = 58,000 its multiplication
        
                    
             
        
        
        
I don't know if I did this right. 
There are 1097.6 pages in the book. I multiplied .35 by 56 and got 19.6. I multiplied 19.6 by 56 and got 1097.6. Therefore, there are 1097.6 pages in the book.
        
             
        
        
        
PR : RC = PQ :  AC
so,
PQ  = 2.8 inches
Hope this helps
