II. Find the area of each composite figures. Write your solutions and answer. Use , π = 3.14
1. A = (πr²)/2 + (½ × b × h)
A = (3.14) × (3×3)/2 + (½ × 6× 8)
A = (3.14 × 9)/2 + (40/2)
A = (14.13 + 24
A = 38.13cm
2. A = (½ × b × h) + ( L × W)
= (½ × 8 × 9.5) + (19.5 × 9.5)
= (75/2) + 185.25
= 38 + 185.25
A = 223.25m
3. A = (πr²) + (πr²)/2) + (s × s)
= (3.14 × 6 × 6) + (3.14 × 6×6)/2 (12×12)
= 113.04 + 56.52 + 144
A = 169.56cm
4. A = (πr²)/2 + (L×W)
= (3.14 × (4.5 × 4.5)/2 + (18 × 9)
= (3.14 × 20.25)/2 + 162
= (63.59)/2 + 162 = 26.80+ 162 = 188.80
