A standard drinking straw is 19.5 cm long and has a diameter of 0.6 cm. How many square centimeters of plastic are used in one straw? *please help i will medal*

So basically you are finding the surface area of a cylinder. SA = 2πrh + 2B R = radius of base H = Height B = area of base Tip: a straw doesn't use plastic at the two bases.

So it would be 36.8 cm then?
