Question 4: A circular pizza has a diameter of 14 inches. What is the area of the pizza? (Use π ≈ 3.14)
- 43.96 in²
- 87.92 in²
- 153.86 in² (Correct answer)
- 615.44 in²
Correct answer: 153.86 in²
Radius = 7 in; Area = π × r² = 3.14 × 49 ≈ 153.86 in².
Question 5: Which of the following represents the number 4,302,015 in expanded form?
- 4,000,000 + 300,000 + 2,000 + 15
- 4,000,000 + 300,000 + 20,000 + 15
- 4,000,000 + 302,000 + 15
- 4,000,000 + 300,000 + 2,000 + 10 + 5 (Correct answer)
Correct answer: 4,000,000 + 300,000 + 2,000 + 10 + 5
4,302,015 = 4,000,000 + 300,000 + 2,000 + 10 + 5.
