How do i find the volume of a Paper Cup?

To find the volume of a paper cup, you'll need to measure its dimensions and then use the formula for the volume of a cylinder. Here's how you can do it:

Measurements: Measure the height (h) of the paper cup and the diameter (d) of its circular opening. Make sure to measure in the same unit, such as inches or centimeters.

Radius Calculation: Since you have the diameter (d), you can find the radius (r) by dividing the diameter by 2.

So, in summary, the steps are:

Measure the height and diameter of the paper cup.
Calculate the radius.
Use the volume formula for a cylinder.
Perform the calculations.
Include units in your final answer.
