Mathematics in Science
All this science has made you a little thirsty, so you head for the food court to grab something to drink.
The museum's food court offers soft drinks in a regular cup 4 centimeters in diameter and 6 centimeters tall, and a novelty test tube 2 centimeters in diameter and 24 centimeters tall. You're really thirsty, so you ask the cashier which one's larger.
"You seem like a smart kid," he says. "Which one do you think?"
You think for a moment and then pull out your trusty URA Provided Formulas Sheet, which tells you that the volume of a cylinder is π * r² * h. "Ah," you say, "I've got it..."
"...the regular one is bigger!"
"...the novelty test tube is bigger!"
"...they're exactly the same size!"
