Question 1096357: An empty cylindrical glass tube has radius r cm and its height is 20cm. A plastic container contains 1 litre of liquid solution. Solution is transferred from the plastic container to the tube. When the tube is full, 80ml of solution is left in the plastic container.
a) What is the volume of the glass tube?

1 liter = 1000ml
1000-80 = 920ml is the volume of the glass tube.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
r^2Pi20 = volume of glass tube
r^2Pi20 = 920
r^2(62.83) = 920
r^2 = 14.64
r = sqrt14.64
r = 3.83 if you need to know, the radius of the glass cylinder is 3.83cm
