Brian works in the lab and feels an empty cylindrical flask with 200 cubic centimeters of liquid. The flask has a radius of 3 cm and a height of 12 cm. What percent of the volume of the flask is not filled with liquid?

49.49%

Step-by-step explanation:

volume of liquid in the flask = 200 cm^3

radius of the flask = 3 cm

height of the flask = 12 cm

volume of flask is given by =

putting values and solving we get = 396 cm^3

therefore the volume unfilled = 396-200 = 196cm^3

therefore % of volume unfilled = 196/396*100 = 49.49%
