How would you divide this shape up? A rectangle and 2 semi-circles
A3 A1 A2 Atotal = A1 + A2 + A3
Atotal = A1 + A2 + A3 A1 A2 A3
Atotal = A1 - A2 How? A1 A2
Find the area: 10 cm A1 2 cm 7 cm A = A1 + A2 12 cm A2 = 10x2 + 10x3 10 cm = 20 + 30 = 50 cm2 3 cm
Find the area of the yellow region 10cm A = r2 Ay = A1 - A2 A1 Ay = (10)2 - (3)2 Ay = 100 - 9 3 Ay = 285.7 cm2 A2
