An arc on a circle measures [tex]295^{\circ}[/tex]. The measure of the central angle, in radians, is within which range?

A. [tex]\(0\)[/tex] to [tex]\(\frac{\pi}{2}\)[/tex] radians
B. [tex]\(\frac{\pi}{2}\)[/tex] to [tex]\(\pi\)[/tex] radians
C. [tex]\(\pi\)[/tex] to [tex]\(\frac{3\pi}{2}\)[/tex] radians
D. [tex]\(\frac{3\pi}{2}\)[/tex] to [tex]\(2\pi\)[/tex] radians



Answer :

To determine the measure of a central angle in radians and identify which range it falls into, follow these steps:

### Step-by-Step Solution:

1. Convert Degrees to Radians:
- First, we need to convert the angle from degrees to radians. The formula to convert degrees to radians is:
[tex]\[ \text{angle in radians} = \text{angle in degrees} \times \left(\frac{\pi}{180}\right) \][/tex]
- For an angle of [tex]\(295^{\circ}\)[/tex]:
[tex]\[ \text{angle in radians} = 295 \times \left(\frac{\pi}{180}\right) \][/tex]

2. Calculate the Angle in Radians:
- Perform the calculation:
[tex]\[ \text{angle in radians} = 295 \times \left(\frac{\pi}{180}\right) \approx 5.1487212933832724 \][/tex]

3. Determine the Range:
- Now, compare the calculated angle in radians with the given ranges:
[tex]\[ \begin{aligned} 0 & \quad \text{to} \quad \frac{\pi}{2} \quad (\approx 0 \text{ to } 1.5708) \\ \frac{\pi}{2} & \quad \text{to} \quad \pi \quad (\approx 1.5708 \text{ to } 3.1416) \\ \pi & \quad \text{to} \quad \frac{3\pi}{2} \quad (\approx 3.1416 \text{ to } 4.7124) \\ \frac{3\pi}{2} & \quad \text{to} \quad 2\pi \quad (\approx 4.7124 \text{ to } 6.2832) \\ \end{aligned} \][/tex]
- Comparing [tex]\(5.1487212933832724\)[/tex] with these ranges:
[tex]\[ 4.7124 \quad \text{to} \quad 6.2832 \][/tex]

4. Conclusion:
- The angle [tex]\(5.1487212933832724\)[/tex] radians falls within the range:
[tex]\[ \frac{3\pi}{2} \quad \text{to} \quad 2\pi \quad (\approx 270^{\circ} \text{ to } 360^{\circ}) \][/tex]

### Final Answer:
The measure of the central angle in radians, [tex]\(5.1487212933832724\)[/tex], is within the range:
[tex]\[ \frac{3\pi}{2} \quad \text{to} \quad 2\pi \quad \text{radians} \][/tex]
