CLAST Geometry and Measurement 2 — Questions and Answers
Question 1: What is the area of a circle with radius 7 cm? (Use π ≈ 3.14)
- 43.96 cm²
- 153.86 cm² (Correct answer)
- 44 cm²
- 153 cm²
Correct answer: 153.86 cm²
Area = π × r² = 3.14 × 49 = 153.86 cm².
Question 2: Two parallel lines are cut by a transversal. Which pair of angles is always equal?
- Co-interior angles
- Supplementary angles
- Alternate interior angles (Correct answer)
- Adjacent angles
Correct answer: Alternate interior angles
Alternate interior angles formed by a transversal cutting parallel lines are always congruent.
Question 3: A square has an area of 64 cm². What is the length of one side?
- 6 cm
- 7 cm
- 8 cm (Correct answer)
- 9 cm
Correct answer: 8 cm
Area = side²; side = √64 = 8 cm.
Question 4: What type of triangle has all three sides of equal length?
- Scalene
- Isosceles
- Equilateral (Correct answer)
- Right
Correct answer: Equilateral
An equilateral triangle has all three sides equal and all three angles equal to 60°.
Question 5: Convert 5 feet to inches.
- 50 inches
- 55 inches
- 60 inches (Correct answer)
- 65 inches
Correct answer: 60 inches
There are 12 inches in 1 foot; 5 × 12 = 60 inches.
Question 6: What is the surface area of a cube with side length 3 cm?
- 27 cm²
- 36 cm²
- 54 cm² (Correct answer)
- 72 cm²
Correct answer: 54 cm²
A cube has 6 faces; each face area = 3² = 9 cm²; total surface area = 6 × 9 = 54 cm².
