The number of radians in a 720-degree angle can be written as aπ, where a is a constant. What is the value of a?
Correct answer: B. 4
- A. 3
- B. 4
- C. 5
- D. 6
Explanation
The correct answer is 4. To convert degrees to radians, use the formula: Radians = Degrees × (π/180). For a 720-degree angle, the calculation is: 720 × (π/180) = 4π. Thus, the value of a is 4. Option A (3) represents 540 degrees, Option C (5) represents 900 degrees, and Option D (6) represents 1080 degrees.
