A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 9in and a diameter of 8in. The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company makes 15 labels, how many square inches of paper will be needed? Use 3.14 for π, and do not round your answer.

423

Step-by-step explanation:

Firstly we need to find the circumference of the circle.

Circumference = 2 × Radius with Pi

=2×8×3.14= 50.24

Now we must find the area of 1 label.

Area of 1 label= 3.14 × 9= 28.26cm²

Multiplying by the number of labels =

28.26 × 15

= 423.9 cm²

So, we'll just keep the answer 423 because we were asked how many square inches of paper will be needed.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
