Question 2: What is the perimeter of a square with a side length of 9 inches?
- 81 in
- 18 in
- 36 in (Correct answer)
- 27 in
Correct answer: 36 in
Perimeter of a square is 4 times the side: 4 × 9 = 36 in.
Question 3: A cube has an edge length of 4 cm. What is its volume?
- 16 cm³
- 12 cm³
- 64 cm³ (Correct answer)
- 48 cm³
Correct answer: 64 cm³
Volume of a cube is edge cubed: 4³ = 64 cm³.
Question 4: What is the area of a triangle with a base of 10 m and a height of 6 m?
- 30 m² (Correct answer)
- 60 m²
- 16 m²
- 45 m²
Correct answer: 30 m²
Triangle area is half the base times height: ½ × 10 × 6 = 30 m².
Question 5: A circle has a radius of 7 cm. Using π ≈ 22/7, what is its area?
- 44 cm²
- 154 cm² (Correct answer)
- 22 cm²
- 308 cm²
Correct answer: 154 cm²
Area is πr² = 22/7 × 7 × 7 = 154 cm².
