West B Test Math: Geometry and Measurement 2 — Questions and Answers
Question 1: A rectangular swimming pool is 25 meters long and 10 meters wide. What is the perimeter of the pool?
- 35 meters
- 250 meters
- 70 meters (Correct answer)
- 60 meters
Correct answer: 70 meters
Perimeter of a rectangle = 2(l + w) = 2(25 + 10) = 2(35) = 70 meters.
Question 2: Which of the following best describes supplementary angles?
- Two angles that sum to 90°
- Two angles that sum to 180° (Correct answer)
- Two angles that are equal
- Two angles that sum to 360°
Correct answer: Two angles that sum to 180°
Supplementary angles are two angles whose measures add up to 180 degrees.
Question 3: A triangle has sides measuring 5 cm, 12 cm, and 13 cm. What type of triangle is this?
- Acute triangle
- Obtuse triangle
- Right triangle (Correct answer)
- Equilateral triangle
Correct answer: Right triangle
Since 5² + 12² = 25 + 144 = 169 = 13², by the Pythagorean theorem this is a right triangle.
Question 4: What is the volume of a cube with a side length of 4 cm?
- 16 cm³
- 48 cm³
- 64 cm³ (Correct answer)
- 96 cm³
Correct answer: 64 cm³
Volume of a cube = s³ = 4³ = 64 cm³.
Question 5: An angle measuring 135° is best classified as which type?
- Acute
- Right
- Obtuse (Correct answer)
- Straight
Correct answer: Obtuse
An obtuse angle measures more than 90° but less than 180°, so 135° is obtuse.
Question 6: A circle has a diameter of 14 inches. What is its circumference? (Use π ≈ 3.14)
- 21.98 in
- 43.96 in (Correct answer)
- 153.86 in
- 87.92 in
Correct answer: 43.96 in
Circumference = πd = 3.14 × 14 = 43.96 inches.
Question 7: Which transformation moves every point of a figure the same distance in the same direction?
- Rotation
- Reflection
- Dilation
- Translation (Correct answer)
Correct answer: Translation
A translation slides every point of a figure the same distance in the same direction without rotating or flipping it.
