<h3>Answer:</h3>

414.48 square feet is needed to make 3 dozen of the covers.

<h3>Step-by-step explanation:</h3><h3>Step 1: Find the circumference, perimeter, of the circle.</h3>

To find the circumference, you multiply the 4 by π, and π is 3.14, and you get  12.56.

<h3>Step 2: Find the area of the side, not including the circle.</h3>

The 12.56 is literally the length of the side. The width is the height of the cover which is 10 inches. 12.56 multiplied by 10 is 125.6 square inches.

Step 3: Add them up.

125.6 + 12.56 is 138.16

<h3>Step 4: Multiply 138.16 by three dozen (36 [a dozen is 12]).</h3>

138.16 multiplied by 36 is 4973.76 square inches.

<h3>Step 5: Convert 4973.76 square <u>inches</u> to square <u>feet</u>.</h3>

12 inches is 1 foot so we divide 4973.76 by 12. You get 414.48 square feet.

How do u do this one?
Leto [7]

Answer: 200 messages

========================================================

Check out brainly.com/question/11754609 for a similar problem

Plan A's cost equation is y = 0.10x + 30

Plan B's cost equation is y = 50

Equate the two right hand sides, then solve for x

0.10x + 30 = 50

0.10x = 50-30

0.10x = 20

x = 20/0.10

x = 200

If you send/receive 200 messages, then the two plans will both cost the same ($50) per month.
