~Psst, hey kid~
I believe the answer is false, because y = 10x means the x, (1) is being multiplied by 10, also it's a negative, and 10x is a positive equation.
Hope this helped...
The line y = (1/2)x + 2 has a slope of 1/2 and a y-intercept of 2. Since
the actual inequality is that y > (1/2)x + 2, then the shaded
portion that satisfies this inequality will be above the line. Its
y-intercept at (0, 2) means that the origin is below this line, so the
origin is NOT included in the shaded region, and the shaded region is
above the line. (This is the 1st choice).

Answer:
The surface area of the cylinder is 276.32m²
Step-by-step explanation:
To solve this problem we have to calculate the circle area and the lateral area
To calculate the area of the circle we use the following formula
a = area
r = radius = 2m
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (2m)²
a = 3.14 * 4m²
a = 12.56m²
The area of the circle is 12.56m²
To calculate the lateral area of the cylinder we use the following formula
a = area =
h = heighti = 20m
r = radius = 2m
π = 3.14
a = 2 * π * r * h
we replace with the known values
a = 2 * 3.14 * 2m * 20m
a = 6.28 * 40m²
a = 251.2m²
The lateral area of the cylinder is 251.2m²
Now we add the lateral area of the cylinder with 2 times the area of the circle and obtain the area of the cylinder
251.2m² + (2 * 12.56m²) = 276.32m²
The surface area of the cylinder is 276.32m²
