## Does Activity find the area of a circle?

The geometrical formula to determine the area (A) of a circle of radius r is given by A = πr². Step 1: Draw any circle on a sheet of white paper. Let its radius be r units. Step 2: Draw eight diameters dividing the circle into 16 equal parts.

**How do you teach the area of a circle?**

Finding the Area of a Circle

- Step 1: Identify the radius (r). The radius is the distance from the center of the circle to a point on the circle (the distance halfway across the circle).
- Step 2: Plug r into the formula.
- Step 3: Simplify. Make sure to follow the order of operations (PEMDAS).
