Problem 1 :

The cylindrical Giant Ocean Tank at the New England      Aquarium in Boston is 24 feet deep and has a radius of 18.8 feet. Find the volume of the tank. Use the approximate of value of  , that is 3.14 and round your answer to the nearest tenth if necessary.

Solution :

Step 1 :

Because the tank is in the shape of cylinder, we can use the formula of volume of a cylinder to find volume of the tank.

V  =  r²h cubic units

Step 2 :

Substitute the given measures.

≈  3.14 · 18.8² · 24

(Here deep 24 feet is considered as height)

Simplify.

≈  3.14 · 353.44 · 24

≈  26635.2

Hence, the volume of the tank is about 26635.2 cubic feet.

Let us look at the next problem on "Volume of cylinders word problems worksheet"

Problem 2 :

A standard-size bass drum has a diameter of 22 inches  and is 18 inches deep. Find the volume of this drum. Use the approximate of value of  , that is 3.14 and round your answer to the nearest tenth if necessary.

Solution :

Step 1 :

Usually the bass drum would be in the shape of cylinder. So, we can use the formula of volume of a cylinder, to find volume of the bass drum.

V  =  r²h cubic units ----- (1)

Step 2 :

To find the volume, we need the radius of the cylinder. But, the diameter is given, that is 22 in. So, find the radius.

r  =  diameter / 2

r  =  22/2

r  =  11

Step 3 :

Plug ∏ ≈  3.14, r = 11 and h = 18 in (1).

≈  3.14 · 11² · 18

(Here deep 18 inches is considered as height)

Simplify.

≈  3.14 · 121 · 18

≈  6838.9

Hence, the volume of the bass drum is about 6838.9 cubic inches.

Let us look at the next problem on "Volume of cylinders word problems worksheet"

Problem 3 :

A barrel of crude oil contains about 5.61 cubic feet of oil. How many barrels of oil are contained in 1 mile of a pipeline that has an inside diameter of 6 inches and is completely filled with oil ? How much is “1 mile” of oil in this pipeline worth at a price of \$100 per barrel ?

Solution :

Step 1 :

Usually the pipe line would be in the shape of cylinder. So, we can use the formula of volume of a cylinder to find volume of the crude oil in the pipe line.

V  =  r²h cubic units ----- (1)

Step 2 :

To find the volume, we need the radius of the cylinder. But, the diameter is given, that is 6 in. So, find the radius.

r  =  diameter / 2

r  =  6/2

r  =  3 inches

Step 3 :

Convert the inches into feet by multiplying 1/12.

Because,

1 inch  =  1/12 feet

So, we have

r  =  3 x 1/12 feet

r  =  1/4 feet

Step 4 :

Convert the length of the pipeline from miles to feet.

1 mile  =  5280 feet

So, we have

length  =  1 mile

length  =  1 x 5280 feet

length  =  5280 feet

Step 5 :

Plug ∏ ≈  3.14, r = 1/4 and h = 5280 in (1).

≈  3.14 · (1/4)² · 5280

(Here , the length 5280 feet is considered as height)

Simplify.

≈  3.14 · (1/16) · 5280

≈  1036.2 cubic feet

Step 6 :

To find how many barrels of oil are contained in 1 mile of a pipeline, divide the volume of crude oil in the pipeline (1036.2 cu.ft) by 5.61.

Because a barrel of crude oil contains about 5.61 cubic feet of oil.

So, number of barrels of oil are contained in 1 mile of a pipeline is

=  1036.2 / 5.61

=  184.7

There are about 184.7 barrels of oil are contained in 1 mile of a pipeline.

Step 7 :

Find the worth of “1 mile” of oil in the pipeline at a price of \$100 per barrel.

No. of barrels of oil in 1 mile of a pipeline  =  184.7

So, the worth of “1 mile” of oil in the pipeline is

=  \$100 x 184.7

=  \$18,470

The worth of “1 mile” of oil in the pipeline at a price of \$100 per barrel is about \$18,470.

Let us look at the next problem on "Volume of cylinders word problems worksheet"

Problem 4 :

A pan for baking French bread is shaped like half a cylinder as shown in the figure. Find the volume of uncooked dough that would fill this pan. Use the approximate of value of  , that is 3.14 and round your answer to the nearest tenth if necessary.

Solution :

Step 1 :

Because the pan is shaped like half a cylinder, we can use the formula of volume of a cylinder to find volume of uncooked dough that would fill this pan

V  =  1/2 · r²h cubic units ----- (1)

(Because the pan is shaped like half a cylinder, 1/2 is multiplied by the formula of volume of a cylinder)

Step 2 :

To find the volume, we need the radius of the cylinder. But, the diameter is given, that is 3.5 in. So, find the radius.

r  =  diameter / 2

r  =  3.5/2

r  =  1.75

Step 3 :

Plug ∏ ≈  3.14, r = 1.75 and h = 12 in (1).

≈  1/2 · 3.14 · 1.75² · 12

Simplify.

≈  1/2 · 3.14 · 3.0625 · 12

≈  57.7

Hence, the volume of uncooked dough that would fill the pan is about 57.7 cu.inches.
