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:
I think it's 4?
Step-by-step explanation:
I used Desmos, a graphing calculator. After plotting the points and drawing a line, I counted 4 points up and 1 point over to get to the next point. 4/1 =4
