## Math Fact

Did you know that geometry is one of the oldest mathematical sciences? It was formally created by Euclid in the 3rd century BC. That is over 2300 years ago. If you are my student, about 15 years old, that means it is about 153 times older than you. And you thought your grandparents were old.

## Famous Math Quote

If you think dogs can't count, try putting three dog biscuits in your pocket and then giving Fido only two of them.

# Announcements

To all the students I taught at West, I hope I made a positive impact on your life. I've accepted a new job as a computer consultant, and I've decided to use what I've learned in my new profession to try and continue working on this website as I've taken about a year and a half off of adding any real substance to this website. If you find any problems with any of my pages, please email me at Eric_Douce@yahoo.com.

## Finding Sector Area of a Circle

#### In this video, I explain the definition of a sector and how to find the sector area of a circle. I work 2 example problems, one for finding the sector of a circle and the other to find the radius of a circle with a given sector area.

## Disclaimer

This website is dedicated to mostly geometry because I'm a geometry teacher. At some point, I plan on putting basic math up to calculus on this website. Included on this website will be videos of geometry throughout the year, interactive practice where you can practice your math skills, and copies of lessons and homework. Keep in mind this is a work in progress. I'm adding to this website as time goes by. I probably won't be able to complete every part of this website this year.
