PLS ADD EXPLANATION
Cylinder radius is 2 cm height is 10cm what is the surface area

150.83 (cm²).

Step-by-step explanation:

1) the area of the bottom and top is: A₁=π*r²*2=2*3.1415*4≈25.13 (cm²);

2) the length of the circle in the bottom/top side is: l=2*π*r=2*3.1415*8≈12.57 (cm);

3) the area of the side surface of the cylinder is: A₂=l*h=12.57*10=125.7 (cm²);

4) the required area of the cylinder is:

A=A₁+A₂=25.13+125.7=150.83 (cm²).

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
