The mean score is 3.08.
There is 1 quiz with score 1, so 1 point; 3 quizzes with score 2 for 3*2 = 6 points; 4 quizzes with score 3 for 4*3 = 12 points; 4 quizzes with score 4 for 4*4 = 16 points; and 1 quiz with score 5 for 5 points.
This is a total of 1+6+12+16+5 = 40 points.
This is out of 1+3+4+4+1 = 13 quizzes.
40/13 = 3.08
        
             
        
        
        
Answer:
Lateral area  =
 
pi *  (radius) * √ [ height ^2  + radius^2 ]  =
 
pi *  ( 4 )  * √ [  4^2 + 3^2 ]  =
 
pi * ( 4 ) * √25  =
 
pi * ( 4 ) * (5 )  =
 
20 pi  units^2  ≈   62.8 units^2
