Acylindrical piece of iron pipe is shown below. the wall of the pipe is 1.25 inches thick.
what is the approximate inside volume of the pipe?
69 cubic inches
99 cubic inches
332 cubic inches
703 cubic inches

332 cubic inches

Step-by-step explanation:

Given : Height of cylinder = 14 inches

           Diameter of Base(including thickness = 8 inches

           The wall of the pipe is 1.25 inches thick.

To find: What is the approximate inside volume of the pipe?

Solution:

Diameter including thickness = 8 inches

Since thickness of wall = 1.25 inches

So, diameter excluding thickness from both sides =

                                                                                   =

                                                                                   =

Thus the diameter excluding thickness = 5.5 inches

Radius of cylinder =

Volume of cylinder =

Where r is the radius

h is the height

Substitute the values .

Volume of cylinder =

                              =

Thus the approximate volume of cylinder is 332 cubic inches.

Hence Option C is correct.
