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

A. 0 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 within which range the arc measure of [tex]\(295^\circ\)[/tex] falls in the context of radians, we need to follow these steps:

1. Convert the arc measure from degrees to radians:

To convert degrees to radians, use the formula:
[tex]\[ \text{radians} = \text{degrees} \times \frac{\pi}{180} \][/tex]
For an arc measure of [tex]\(295^\circ\)[/tex]:
[tex]\[ 295^\circ \times \frac{\pi}{180} = \frac{295\pi}{180} \approx 5.1487212933832724 \text{ radians} \][/tex]

2. Determine the range in which the central angle falls:

The possible ranges for the central angle, in radians, are:
- [tex]\(0 \text{ to } \frac{\pi}{2} \text{ radians}\)[/tex]
- [tex]\(\frac{\pi}{2} \text{ to } \pi \text{ radians}\)[/tex]
- [tex]\(\pi \text{ to } \frac{3\pi}{2} \text{ radians}\)[/tex]
- [tex]\(\frac{3\pi}{2} \text{ to } 2\pi \text{ radians}\)[/tex]

Let's convert these to approximate decimal values for easier comparison:
- [tex]\(\frac{\pi}{2} \approx 1.5708\)[/tex]
- [tex]\(\pi \approx 3.1416\)[/tex]
- [tex]\(\frac{3\pi}{2} \approx 4.7124\)[/tex]
- [tex]\(2\pi \approx 6.2832\)[/tex]

Now, we find that:
- [tex]\(0\)[/tex] to [tex]\(1.5708\)[/tex] radians does not include [tex]\(5.1487\)[/tex] radians
- [tex]\(1.5708\)[/tex] to [tex]\(3.1416\)[/tex] radians does not include [tex]\(5.1487\)[/tex] radians
- [tex]\(3.1416\)[/tex] to [tex]\(4.7124\)[/tex] radians does not include [tex]\(5.1487\)[/tex] radians
- [tex]\(4.7124\)[/tex] to [tex]\(6.2832\)[/tex] radians does include [tex]\(5.1487\)[/tex] radians

Therefore, the arc measure of [tex]\(295^\circ\)[/tex] falls within the range [tex]\(\frac{3\pi}{2} \text{ to } 2\pi\)[/tex] radians. So, the measure of the central angle, when expressed in radians, is in the range:
[tex]\[ \boxed{\frac{3\pi}{2} \text{ to } 2\pi \text{ radians}} \][/tex]
