You can put this solution on YOUR website! A drinking glass is in the shape of a cylinder that is 60mm in diameter and 15mm tall. How many cubic centimeters of water will it hold?
This question is asking for the volume of the cylinder.
We need the formula V = pi(r)^2 h
If the diameter is 60mm, then the radius is 1/2 of the diameter or 30mm.
We are given the height to be 15mm.
We now plug and chug.
V = pi(30)^2(15)
V = 13,500pi....This is an answer in terms of pi.
If you must use the value of pi, then use the fact that pi = 3.14.
V = (3.14)(13,500)
V = 42,390mm^3
