An arc of circle M has a length of 32 centimeters, and the corresponding central angle has a radian measure of [tex] \theta [/tex]. What is the radius of the circle?

The radius of the circle is _____ centimeters.


Sagot :

To determine the radius of the circle, given the arc length and the central angle in radians, follow these steps:

1. Understand the relationship: The formula that associates the arc length ([tex]\(s\)[/tex]), the radius ([tex]\(r\)[/tex]), and the central angle in radians ([tex]\(\theta\)[/tex]) is:
[tex]\[ s = r \cdot \theta \][/tex]
In this formula:
- [tex]\(s\)[/tex] represents the arc length.
- [tex]\(r\)[/tex] is the radius of the circle.
- [tex]\(\theta\)[/tex] is the central angle in radians.

2. Identify the given values:
- Arc length, [tex]\(s = 32\)[/tex] centimeters.
- Central angle in radians, [tex]\(\theta = 1\)[/tex].

3. Rearrange the formula to solve for the radius, [tex]\(r\)[/tex]:
[tex]\[ r = \frac{s}{\theta} \][/tex]

4. Substitute the given values:
[tex]\[ r = \frac{32}{1} \][/tex]

5. Perform the division:
[tex]\[ r = 32 \text{ centimeters} \][/tex]

So, the radius of the circle is [tex]\(32\)[/tex] centimeters.
