What is the volume of a right circular cylinder with a diameter of 8 cm and a height
of 18 cm ?

To find the volume of a right circular cylinder, you can use the formula:

First, you need to find the radius. Given the diameter is 8 cm, the radius is half of that:

Next, plug the radius and height into the formula:

Hence, the volume is .

Did you know that the use of cylinders goes back to ancient times? Ancient Greeks used cylindrical shapes in various structures and artworks. They even built grand columns that resemble cylinders, which not only served functional purposes but also influenced architectural styles for centuries, proving that math isn’t just numbers—it’s in the very foundation of beautiful architecture!

In real life, the applications of volume calculations for cylinders are everywhere! From determining how much liquid a soda can hold to estimating the amount of concrete needed for a cylindrical column, this formula helps visualize and manage various everyday items. So next time you sip from a can, you can appreciate the engineering (and math!) that helped create that perfect volume for your beverage!
