Question
A laboratory supply company produces graduated cylinders, each with an internal radius of 2 inches and an internal height between 7.75 inches and 8 inches. What is one possible volume, rounded to the nearest cubic inch, of a graduated cylinder produced by this company?
The correct answer is: 97
volume of a cylinder, V = πr2h
r = radius = 2 inches
h = height = between 7.75 and 8 inches
there are many possible values depending on the value of h. any value of h is valid between 7.75 and 8 inches. But the question asked for just one possible value, so will be using just h = 7.75
v = π x 22 x 7.75
v = 97.4
= 97 to the nearest cubic inch
