Answer:

First set: 0.95. Second set: 0.86. Third set: 0.88.

Step-by-step explanation:

Imagine that these are not decimals, they are regular numbers (for example: 0.88 is turned into 88). You would determine which one is the greatest depending on which one is higher (like 44 is higher than 32). Therefor the first set: 0.95 the second set: 0.86 the third set: 0.88.

The answer is:  " 471 cm² " .
_____________________________________________________
The formula for the surface area, "S.A.", of a "cylinder":

S.A. =  2 π r² + 2 π r h ; 

in which:

"S.A." = "surface area" of the cylinder; for which we wish to solve; 

 π = 3.14 (approximation we shall use) ;

  r = radius = 5 cm (given; from figure); 

  h = height = 2 cm (given; from figure);
______________________________________
To solve for the surface area, "S.A." . let us plug in our known values, and solve:


S.A. =  2 π r²   +    2 π r h  ; 


S.A. = 2 * (3.14) * (5 cm)²  +  2 * (3.14) * (5 cm) * 10 cm)  ;

        = 2 * (3.14) * (5²) * (cm²)   +    2 * (3.14) * 5* 10 * cm² ;

        = 2 * (3.14) * (25) * (cm²)  +    2 * (3.14) * 5* 10 * cm²  ;

        = 157 cm²  +  314 cm²  ;

        =  471 cm² .

The answer is:  " 471 cm² " .
