To measure the length of the curved part of the base of a tumbler or bottle, you need to measure the circumference of the base. This can be done using a flexible measuring tape or a piece of string.
Here’s how to do it:
Choose a measuring tool: Use a flexible measuring tape or a piece of string.
Wrap the tool around the base: Wrap the measuring tape or string around the curved part of the base, ensuring it’s snug but not too tight.
Mark the meeting point: If using string, mark where the ends meet.
Measure the string: Use a ruler to measure the length of the string between the marks.
Record the measurement: Write down the length of the string (or the measurement from the measuring tape). This is the circumference of the base, which represents the length of the curved part.
