Nila : What is the area of the circle ?

Me : Take a measuring tape and measure your head in inches. If you are a medium sized head like me , its 22 inches. divide 22 by 3.14, which is 7.006 and it the diameter of the circle aka(2R).

Nila : what’s the Circumference Of the circle ?

Me : 2 * PI * R

Nila : what is the area of the circle ?

Me : PI * R * R

Nila : what is the area of the triangle ?

Me: 1/2 * b * h . when the height of the triangle is equal to the circumference of the circle( 2 * pi * r).

1/2 * R * (2 * pi * R) = Pi * R * R = Area of the circle .

Nila : The circle becomes a triangle. Its an oxymoron.

Me : What is the rate of change at a given instant ?

Nila : we need two points to calculate the rate of change.
