A barrel of crude oil contains about 5.61 cubic feet of oil. How many barrels of oil contained in 1 mile (5280 feet) of a pipeli
8_murik_8 [283]
1)volume of the  pipeline

The pipeline is a cylinder, therefore;
Volume (cylinder)=πr²h
r=radius
h=height of the cylinder

diameter=6 in*(1 ft / 12 in)=0.5 ft
raius=diameter / 2=0.5 ft / 2=0.25 ft.
height=5280 ft

Volume (pipeline)=π(0.25 ft)²(5280 ft)=330π ft³≈1036.73 ft³.


2) we calculate the number of barrel
1 mile of oil in this pipeline is 330π ft³ of oil.

1 barrel of crude------------------5.61 ft³
x----------------------------------330π ft³

x=(1 barrel*330π ft³) / 5.61 ft³=184.8 barrels

3) we calculate the price.

1 barrel---------------$100
184.8 barrels----------  x

x=(184.8 barrels * $100) / 1 barrel=$18,480

Solution: ≈$18,480

Jan and two of her friends raised money by having a bake sale. They split the proceeds. If each person received $32.19, how much
AveGali [126]

Answer: 1. Equation =3x = M , where x = money each received and M= total money received.

2.total money from bake sale=$96.57

Step-by-step explanation:

STEP 1

Let the total money receive from proceeds be = M

and let the amount of money each receive after the split  = x

Since   Jan and her two friends raised the money together, the total proceeds will be calculated using the equation

x+x+x= M

3 x = M ---- Equation

STEP 2--- Solving

if 3 x= M

and x =mount of money each receive after the split=$32.19

Therefore total money from bake sale, M = 3x = 3 x 32.19 = $96.57
