50.24

Step-by-step explanation:

Plug in:

SA=2(3.14)+2(3.14)·4

Now, you would solve with Pemdas:

=4.

SA=2(3.14)×4+2(3.14)×4

2×3.14=6.28

6.28×4+6.28×4

6.28×4=25.12

25.12+25.12=50.24

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
