Answer: 229°
Step-by-step explanation:
Hi, to answer this question we have to multiply the radians by 180/π.
Since we have 4 radians, the expression is:
4 x (180/π) = 229.18 degrees
Rounding to the nearest degree:
229 degrees (because the first number after the point is less than 5 )
Feel free to ask for more if needed or if you did not understand something.
Question:
A. 13°
B. 45°
C. 229°
D. 720°
Answer:
The correct option is;
C. 229°
Step-by-step explanation:
Here we have
360° = 2·π radians which is the angle at the center of a circle, where the circumference of the circle is 2·π·r and r = 1
Therefore;
1 radian = 360°/(2·π)
Hence, 4 radian = 4 × 360°/(2·π) = 720/π = 229.183°
Therefore, the value of 4 radians converted to degrees is 229° after the exact figure is rounded to the nearest whole number.
