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 .

Answer:
Step-by-step explanation:
In scientific notation, the national debt in 2013 was approximately
You can see this by taking the decimal point between the 1 and 6 and moving it 13 places to the right.
The smallest power of 10 that will be larger than this number is .
Answer:
3rd answer
Step-by-step explanation:
If you look at the translation, each point is moved 6 to the right on the X axis, and down 4 on the y- axis. so, therefore it should be (6,-4)
<em>When evaluating 
then we get that the expression is 11</em>
<h2>
Explanation:</h2>
As I understand the expression is the following:
Let's call, that expression as 
So we are asked to find the value of the expression when . In other words, we need to substitute , so:
So <em>when evaluating then we get that the expression is 11</em>
