IBEW Geometry and Measurement 2 — Questions and Answers
Question 1: How many inches are in 4.5 feet?
- 48 inches
- 52 inches
- 54 inches (Correct answer)
- 56 inches
Correct answer: 54 inches
1 foot = 12 inches, so 4.5 × 12 = 54 inches.
Question 2: What is the area of a circle with a radius of 6 feet? (Use π ≈ 3.14)
- 18.84 sq ft
- 37.68 sq ft
- 113.04 sq ft (Correct answer)
- 226.08 sq ft
Correct answer: 113.04 sq ft
Area = π × r² = 3.14 × 6² = 3.14 × 36 = 113.04 sq ft.
Question 3: A rectangle has a length of 12 ft and a width of 5 ft. What is the length of its diagonal?
- 11 ft
- 13 ft (Correct answer)
- 15 ft
- 17 ft
Correct answer: 13 ft
Diagonal = √(12² + 5²) = √(144 + 25) = √169 = 13 ft.
Question 4: What is the surface area of a cube with a side length of 4 feet?
- 16 sq ft
- 48 sq ft
- 64 sq ft
- 96 sq ft (Correct answer)
Correct answer: 96 sq ft
Surface area of a cube = 6 × side² = 6 × 16 = 96 sq ft.
Question 5: The sum of the interior angles of any triangle always equals:
- 90°
- 180° (Correct answer)
- 270°
- 360°
Correct answer: 180°
The three interior angles of any triangle always sum to exactly 180°.
Question 6: What is the volume of a cylinder with radius 3 ft and height 7 ft? (Use π ≈ 3.14)
- 65.94 cu ft
- 131.88 cu ft
- 197.82 cu ft (Correct answer)
- 263.76 cu ft
Correct answer: 197.82 cu ft
Volume = π × r² × h = 3.14 × 9 × 7 = 197.82 cu ft.
