Step-by-step explanation:
step 1
Find the area of a a 36 inch piece of PVC pipe with an outside diameter of 0.82 inches and an inside diameter of 0.75 inches
The area of a circle is equal to

we have


assume


substitute the values


step 2
Find the volume of the piece of PVC
Multiply the area by its length

step 3
Find the weight of the piece of PVC
Multiply the volume by its density
The density is 
so

(350 + 700) / 2 = 1050/2 = 525...the average of both tanks is 525 gallons
Answer:
2+3=5
Step-by-step explanation:
100x + 300 = 500
100x = 500 - 300
100× = 200
100x/100 = 200/100
therefore ^x = 2
x + 3 = 5
2 + 3 = 5
