## Reflection: Modeling Area of a Circle - Section 1: Lesson Notes + Examples

I went through the examples with a class but found that several students still seemed lost.  I decided the students needed a list to follow.  This will help the majority of students to be independent.

The list is below.

Finding the Area of a Circle

2) Substitute the radius, r, into the formula Area = PI * r^2

3) Solve the equation

I posted this on the board as students worked.  If they had a question, I first made sure they had taken care of the 3 steps on the board.

How do I find the area of a circle again?

# Area of a Circle

Unit 6: Geometry
Lesson 8 of 37

## Big Idea: Students learn to use the area of a circle formula by first seeing how the formula is similar to the area of a rectangle.
