Geometry and Trigonometry practice question
A regular hexagon is inscribed in a circle of radius 6. What is the perimeter of the hexagon?
Answer: 36
A regular hexagon's side equals the radius of its circumscribed circle, so the perimeter is 6 × 6 = 36.
Common wrong answers

- 18 halves the perimeter.
- If you answered 72
- 72 uses the diameter as the side.
- If you answered 37.7
- 37.7 is the circle's circumference.
