Solving Problems With Volume of a Cylinder and Proportional Reasoning
Dan Meyer’s Hot Coffee 3 act math task is my favourite task to use in order to give us a reason to find the volume of a cylinder. Dan has a great summary of this task here, so I’ll just quickly preview what you’ll get when you head to his resource page.

Act 1, Scene 1 – Introduce the Problem
Show students this video.
What is going on in the video? What questions come to mind? What are you wondering?
The question we are going to head towards is:
How many gallons of coffee will fit in the cup?
Act 1, Scene 2 – The Old Record
I’m sure the discussion around why anyone would want a cup of coffee that big will come up at some point.
Show them this video.
Students will see the old record was 750 gallons of coffee. Let them make their predictions on how many gallons the cup in this record breaking attempt will hold.
The video also discusses how long it took to brew the 750 gallons of coffee used in the old record (4 hours). How long will it take for the new “biggest cup” to fill up?
Act 2 – Details
Here’s some details necessary for students to solve the problem:
And you can use Google to determine the conversion from feet-cubed to gallons (1 ft-cubed = 7.4805 US gallons).
Act 3 – The Answer
Show the students this video.
