Remember that the result is the volume of the paper and the cardboard.

Tadaaam! The volume of a hollow cylinder is equal to 742.2 cm 3.

Find out what's the height of the cylinder, for us it's 9 cm.

It's the internal radius of the cardboard part, around 2 cm. Determine the internal cylinder radius.The standard is equal to approximately 5.5 cm.

Enter the external radius of the cylinder.a roll of toilet paper, because why not? :) To calculate the volume of a cylindrical shell, let's take some real-life example, maybe. Stack Exchange network consists of 180 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Where R - external radius, and r - internal radius

The formula behind the volume of a hollow cylinder is:Ĭylinder_volume = π * (R² - r²) * cylinder_height a drinking straw or a pipe - the hollow cylinder is this plastic, metal, or other material part. Other types of optimization problems that commonly come up in calculus are: Maximizing the volume of a box or other container Minimizing the cost or. It's easier to understand that definition imagining e.g. Plugging x 3.681 back into the volume formula gives a maximum volume of V 820.529 in³. The hollow cylinder, also called the cylindrical shell, is a three-dimensional region bounded by two right circular cylinders having the same axis and two parallel annular bases perpendicular to the cylinders' common axis. The first of these is outside the allowable values for x, so the solution is the second.
