find the value of x.\nx≈\n(do not round until the final answer. then round to the nearest tenth as needed.)
Answer
Explanation:
Step1: Apply Pythagorean theorem
In a circle, if a radius is perpendicular to a chord, it bisects the chord. Here, half - of the chord length is $\frac{8}{2}=4$, and the distance from the center of the circle to the chord is 3.1. Let the radius of the circle be $x$. According to the Pythagorean theorem $a^{2}+b^{2}=c^{2}$, where $a = 4$, $b=3.1$, and $c=x$. So $x=\sqrt{4^{2}+3.1^{2}}$.
Step2: Calculate the value of $x$
First, calculate $4^{2}=16$ and $3.1^{2}=9.61$. Then $4^{2}+3.1^{2}=16 + 9.61=25.61$. So $x=\sqrt{25.61}\approx5.1$.
Answer:
$5.1$
