Answer:
1608.5mm²
Step-by-step explanation:
the formula to it is π r²h so 8 times itself or the radius and times it with pi so it equals to 201.0619298297. then you times it with 8 aka the height and you get 1,608.4954386376. then you round it and you get 1608.5. 
 
        
             
        
        
        
Well, it would end up taking Sandy 3 minutes to run the race and Chris 2 and a half minutes. Meaning Sandy crossed the Dubinsky line 30 seconds after Chris.
        
                    
             
        
        
        
So if there are 5 choices and only one is correct, there is a 1/5 chance of being correct. since there was 2 questions, you need to multiply 1/5 by 1/5 to get 2/25 of getting both questions correct.
i hope this helps!!
        
             
        
        
        
1)96/8=12
2)(95*6+5)/6 : (24+1)/3 = (95*6+5)/6 : 2*25/6 = 575/6 *6/50=575/50
=23/2=11 1/2
11 1/2
3) (11 1/2)*12 area of the one  type of the wall, there are 2 such walls
 (11 1/2)*12*2
(8 1/3)*12 area of the second type of the wall, there are 2 such walls
(8 1/3)*12 *2
Altogether area of the walls:
(11 1/2)*12*2 + (8 1/3)*12 *2=12*2(11 1/2 + 8 1/3)= =24(19+3/6+2/6)=24(19+5/6) = 456 +24*(5/6)= 456+20= 476
