What are the 3 steps of going from circumference to area?
1: circumference/3.14 (pi) to get diameter


2: diameter/2 to get radius

3: A= 3.14 x radius squared

Look on the board for compound shape #1 and find the shaded area.
Area of square = 400

Area of circle = 314

400-314= 86cm

Look on the board for 2nd compound shape and solve for area
Area of square = 4

Area of circle = 3.14

4 + 3.14 = 7.14
