If 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?

The given values of this problem are:
Length = 19. 5 cm
Width (diameter) = 0.6 cm

The unknown is: how much square cm of plastic are used in one straw? In other words the area of the straw.

Derivations and solutions:

Area = length x width
Area = 19. 5 cm x 0.6 cm

Area = 11.7 cm(squared) / 11.7 cm^2

The clear answer is clearly 25 is very clear to me

Hey, can you post the problem?
