The volume of the pipe is about 282.6 cubic feet.
First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).
pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7
The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6
Answer:
1. height: 18√2 ≈ 25.46 inches; length: 36√2 ≈ 50.91 inches
2. length: 27 inches; width: 24 inches
Step-by-step explanation:
1. The area of a triangle is given by ...
A = 1/2bh
where b represents the base length, h represents the height.
Filling in the numbers, we get ...
648 in² = 1/2(2h)(h)
h = (√648) in = 18√2 in ≈ 25.46 in
The height is 18√2 inches, about 25.46 inches; the base is 36√2 inches, about 50.91 inches.

2. The area of a rectangle is given by ...
A = lw
where l represents the length, and w represents the width.
Filling in the numbers, we get ...
648 in² = (w+3)(w)
w² +3w -648 = 0 . . . . . . . rearrange to standard form
(w -24)(w +27) = 0 . . . . . . factor
The positive value of w that makes a factor zero is 24.
The length of the poster is 27 inches; the width is 24 inches.
Answer:
second 1
Step-by-step explanation:
It’s 6 because it move up 6 units and 1 unit to the right. Slope is rise over run so it’ll be 6/1 which equal 6
