Access full lesson containing this video at: http://www.yourteacher.com/prealgebra/circumference.php Students learn that the circumference of a circle is the distance around the circle, and the formula for the circumference of a circle is 2 times pi times the radius of the circle. Pi is the ratio of the circumference to the radius, which is approximately 22/7 or 3.14. So a circle with a radius of

Force, F, can come from mass, m, and acceleration, a. F = m a A Force field has a proportional acceleration or gravity, g. F = m g Force can come from two electrical currents. F = i x B = i x uH = i1 x ui2 u = permeability factor on lines of field per current and can have voltage, v, and frequency, f, dependency (assume one to work in smaller voltages - do not want to go to millions

Taking rozeboosje's idea and running with it a little. The technical term for the method employed in this video is called 'exhaustion' and is a basic form of calculus. Edit: The second to last slide has a formula that has omitted pi in error. This video does a better job explaining it and you get to use scissors - http://www.youtube.com/watch?v=5XtxdGcDOW0

Access full lesson containing this video at: http://www.yourteacher.com/prealgebra/areaofacircle.php Students learn that the formula for the area of a circle is pi times radius squared, so the area of a circle that has a radius of 5 inches is pi times 5 squared, or 25 pi square inches. And since pi = 3.14, 25 pi square inches can also be written as 25 times 3.14, or 78.5 square inches. Note that t

Here is a basic lesson on the general equation of a circle. Grade 11 and Grade 12 students will most probably NOT need this. ERRATA: I missed out the square in the (y-2). It should read (y-2)^2. My apologies. Check out www.gaussianmath.com for more lessons on functions and other calculus related topics.
