For it to be a representative sample the selection needs to be completely random.
Answer:
6. 113.1
8. 63.62
Step-by-step explanation:
6. Circle area = π * r² = π * 36 [inch²] ≈ 113.1 [in²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 6 [inch] * 2 = 12 [inch]
8. Circle area = π * r² = π * 20.25 [inch²] ≈ 63.62 [in²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 4.5 [inch] * 2 = 9 [inch]
4,200 meters are in 28% of 15 km
