Charlie is trying to cover the shape shown with paper. He will NOT be covering the top and the bottom. How much paper will he need? (Use 3.14 for π) A) 141.3 square meters
B) 339.12 square meters
C) 423.9 square meters
D) 282.6 square meters

i believe the answer is d.

hope it you! : d

b

step-by-step explanation:

the word superfluous means unnecessary

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

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
