Project Overview
The content started with the Pythagorean Theorem and then went into the distance formula, the equation of a circle, the unit circle, the definition of sine, cosine and tangent, right-triangle trigonometry, area of polygons, area of a circle, and then volumes of many different shapes. The content we covered with our project was finding the volume of many different shapes. We had to find the volume of three circles but we only had to find one circle's volume. We then had to find the volume of the small inner circles in between the bearings and multiply it by three and subtract that from the overall volume. There was then six triangles in the spaces that we had to find the volume for and add it together. The formula we used was V=PIxR^2xH. The math is shown here: Project Description For This project, We found the volume of a fidget spinner. The fidget spinner we are using has 3 sides and holds 4 bearings one for the center and 3 on the outsides as weights. When you look at this spinner you automatically see 3 circles, maybe 4 if you see the middle. There really is 4 circles, and then a space in between all the circles that is unknown. We used that unknown space as a triangle. We can measure the 3 circles but we have to find the unknown shapes for to be able to find the volume of the fidget. We decided to find the volume of a fidget spinner because we were playing with these at the time and it seemed like something we would want to do that would challenge us but not so much where we couldn't do it. The Math The math work we did for this project is shown in the picture above. Reflection on Math To reflect on this math I thought it was fairly simple once I actually took time to look at it and think about it but at first on this project I was having a tough time because I wasn't giving the work the right attention. Reflection on Project To reflect on this project I enjoyed this because it challenged me, but I could've done much better if I actually gave time to it and didn't put it off till the last second. I don't think I would've been able to do this project without Dr. Drew because he lead me in the right direction for the math work and where I had to go but to conclude I enjoyed this project. |
