A liquid beverage is packaged in a cylindrical can

by admin

A liquid beverage is sealed and packaged in a cylindrical can. Measure from the outside, the diameter of the bottom surface is 6cm and the height is 12cm. The side of the can is marked with the words “net content: 340ml”. Please explain whether there is cheating by the merchant through calculation and analysis?

3.14 × (6÷2) 2 × 12
=3.14 × nine × 12
=28.26 × 12
= 339.12 (cubic centimeter)
= 339.12 (ML)
because 339.12 ml & lt; 340 ml, so this manufacturer cheated consumers.
A: this manufacturer cheated consumers
