I’m a journalism student in college, and math is one of the requirements for not only graduation, but also to help me transfer to a four-year school. There are going to be some situations coming my way involving math, so I had better learn about it now.
Math is all around us, especially in sports. I’m a sports fan, and I especially enjoy watching hockey. I’m curious about how a hockey puck is measured in advanced mathematical terms (Volume, Area and Circumference).
Face it, very few people like math. Math is almost everybody's least-favorite subject in school and in life. But math is all around us.
With this illustrative piece, you will first learn how a puck is measured in area and circumference . Second, you will learn how to measure the diameter , so you will know how to determine the radius . Lastly, you will measure the puck by its volume .
KNOWING ITS RADIUS BY KNOWING THE DIAMETER
The diameter of a hockey puck is three inches (stickshack website). You divide the diameter of three inches by two, and you get a radius of 1.5 inches .
KNOWING THE FORMULA FOR AREA AND CIRCUMFERENCE
In the book Elementary Algebra for College Students , Allen R. Angel discusses the formula for area and circumference, which you can use to measure a hockey puck (144).
Area = r (squared) Circumference = 2 r
Keep in mind that = 3.14
KNOWING HOW TO MEASURE THE PUCK BY VOLUME
In the same math textbook, Allen talks about the formula for right circular cylinder , which is used to measure volume (145). And you use that formula to measure the volume of the hockey puck.
Volume = r h
