Converting Long/Lat Decimal Degrees to Degree Minute Seconds
This Video shows how to use Excel to convert Decimal Degrees into Degree Minute Seconds of Longitude and Latitude. The screencast shows how to use the Text to Column tool to separate out the values and basic math function to convert each value from degrees to minutes and seconds. Finally concatenate function is used to string the texts together to the final product of DMS.

Finding the diameter of a circle using Arc Length-Circles-Geometry Help
Geometry Teachers Never Spend Time Trying to Find Materials for Your Lessons Again! Join Our Geometry Teacher Community Today! http://geometrycoach.com/Geometry-Lesson-Plans/?pa=MOOMOOMATH How do you use the arc length of a circle to find the diameter of a circle? We will look at some application problems using sector area and arc length A pie is cut into 6 equal pieces. The arc length of one piece of pie is 5.4 cm. What is the diameter of the pie? So our strategy is to always draw a picture. Let's start by drawing a picture of the pie and assume it is a circular pie. Let's draw 6 equal pieces. If we have 360 degrees divided by into 6 pieces our central angle is going to be 60 degrees. This gives you an idea of what we are working with. What we will do is use a " Proportion Method" to find the circumference, and then use the circumference to calculate diameter. The proportion method it works like this. We take the arc length and put it over the circumference and set it equal to measure of the angle over 360 degrees. So let's plug in what we know. The arc length equals is 5.4 and we don't know circumference which will become x, and angle measure equals 60 degrees. We then cross product1 times x and 6 times 5= 32.4 which equals my circumference. Next we can work backwards to find the diameter. Circumference = Diameter times Pi which is 32.4. So I will take 32.4 and divide it by Pi and I get 10.31 The pie's diameter is 10.31 centimeters. That is how you use the arc length to find diameter of a circle. You may also enjoy...

RELATED RATES: Distance between the person and the plane (KristaKingMath)
► My Applications of Derivatives course: https://www.kristakingmath.com/applications-of-derivatives-course Related rates problems are an application of derivatives and implicit differentiation that allow us to figure out how fast one thing is changing in relation to how fast something else is changing. For example, we might be interested in how fast an airplane is traveling compared to how fast the angle between the plane and an observer on the ground is changing. Related rates problems allow us to do that by using implicit differentiation. We'll usually take the derivative of the equation, taking the derivative of every variable with respect to time t. Then we'll plug in for what we know and solve for the value we're interested in. The key to related rates problems is getting the right equation set up. You need to figure out what equation you can write that will include the value you need to solve for. In addition to that, you may have to come up with a second equation that will give you the value for a missing variable that you need to plug into your first equation. ● ● ● GET EXTRA HELP ● ● ● If you could use some extra help with your math class, then check out Krista’s website // http://www.kristakingmath.com ● ● ● CONNECT WITH KRISTA ● ● ● Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;) Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!” So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.

Surprises in Mathematics
Featuring Dr. Stan Wagon, Professor of Mathematics - Macalester College. There is no better way to get someone's attention than with an assertion that just seems obviously wrong. Math is full of such things. The talk presents several surprising, even shocking, things from elementary mathematics, such as: A square wheel that rolls perfectly smoothly. A device that uses a normal rotating crankshaft to drill perfect square holes. An application of a non-circular wheel to sewage disposal. A shocking cake puzzle. Surprising new formulas for π. Benford's mysterious law of first digits. The Banach-Tarski Paradox, with constructible pieces.
End of Year Math Projects
End of Year projects in sixth grade are open ended, allowing students to pick a topic that they would like to explore on the own. Since students are given little guidance, they are allowed the freedom to find ways that work and don’t work, and see the importance of planning. Mr. Holloway takes you behind the scenes for his End of Year Math projects.
