Step-by-step explanation:
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:
18m
Step-by-step explanation:
3m and 6m.
3mX6m
equals to 12m
y=x-1 is 2=3-1
y=-x+5 is 2=-3+5
Step-by-step explanation:
3=x and 2=y. x y
(3,2)
Now you just substitute the variables (which are the letters) by the numbers of x (3) and y(2) for both of equations
X = 152.
Figure out the angles of the insides of the triangle and then you'll have your answer:
First angle = (supplementary) 180 - 85 = 95
Second angle = (supplementary) 180 - 123 = 57
95 + 57 = 152
152 = the measure of angles one and two
Find the third angle
180 - 152 = 28
Angle x and angle three (28) are supplementary angles so subtract to find x:
180 - 28 = 152
