DCAS DCAS Geometry and Measurement 2 — Questions and Answers
Question 1: A circle has a radius of 6 cm. What is its diameter?
- 12 cm (Correct answer)
- 6 cm
- 18 cm
- 36 cm
Correct answer: 12 cm
The diameter of a circle is twice its radius, so 2 × 6 = 12 cm.
Question 2: Which unit is most appropriate for measuring the length of a football field?
- Yards (Correct answer)
- Inches
- Millimeters
- Miles
Correct answer: Yards
A football field is typically measured in yards (100 yards), making yards the most appropriate unit.
Question 3: What is the area of a triangle with a base of 10 cm and a height of 6 cm?
- 30 cm² (Correct answer)
- 60 cm²
- 16 cm²
- 15 cm²
Correct answer: 30 cm²
The area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 cm².
Question 4: Two lines that never intersect and remain the same distance apart are called:
- Parallel lines (Correct answer)
- Perpendicular lines
- Intersecting lines
- Diagonal lines
Correct answer: Parallel lines
Parallel lines run in the same direction and never meet, staying equidistant from each other.
Question 5: A rectangular room measures 15 feet by 12 feet. What is its area?
- 180 square feet (Correct answer)
- 54 square feet
- 27 square feet
- 90 square feet
Correct answer: 180 square feet
Area = length × width = 15 × 12 = 180 square feet.
Question 6: How many lines of symmetry does a regular hexagon have?
- 6 (Correct answer)
- 3
- 2
- 4
Correct answer: 6
A regular hexagon has 6 lines of symmetry — three through opposite vertices and three through midpoints of opposite sides.
