Question 3: A cylindrical can has a radius of 5 cm and a height of 10 cm. What is its volume? (Use π ≈ 3.14)
- 785 cm³ (Correct answer)
- 314 cm³
- 1570 cm³
- 250 cm³
Correct answer: 785 cm³
Volume = π × r² × h = 3.14 × 25 × 10 = 785 cm³.
Question 4: A student scored 72, 85, 90, 68, and 75 on five tests. What is the mean score?
- 78 (Correct answer)
- 80
