Question 2: What is the area of a circle with a radius of 7 cm? (Use π ≈ 3.14)
- 21.98 cm²
- 43.96 cm²
- 153.86 cm² (Correct answer)
- 219.8 cm²
Correct answer: 153.86 cm²
Area = πr² = 3.14 × 7² = 3.14 × 49 ≈ 153.86 cm².
Question 3: Which of the following sets of numbers is ordered from least to greatest?
- −1, −0.5, 0, 0.25 (Correct answer)
- 0.25, 0, −0.5, −1
- −0.5, −1, 0, 0.25
- 0, −0.5, 0.25, −1
Correct answer: −1, −0.5, 0, 0.25
On the number line, −1 < −0.5 < 0 < 0.25 is the correct ascending order.
Question 4: A student scored 78, 85, 91, 74, and 82 on five tests. What is the mean score?

Mean = (78 + 85 + 91 + 74 + 82) / 5 = 410 / 5 = 82.
Question 5: Which property is illustrated by the equation 5 × (2 + 3) = 5 × 2 + 5 × 3?
- Commutative property
- Associative property
- Distributive property (Correct answer)

- 13
- 17 (Correct answer)
- 19
- 169
Correct answer: 17
√144 = 12 and √25 = 5, so 12 + 5 = 17.
