type the correct answer in the box. use numerals instead of words. a circular pool has a diameter of 30 feet. a section of the top railing with a central angle of 27° is broken and needs to be replaced. what approximate length of railing needs to be replaced? round your answer to one decimal place. about feet of railing needs to be replaced.
Answer
Explanation:
Step1: Find the radius
The diameter $d = 30$ feet, so the radius $r=\frac{d}{2}=\frac{30}{2}=15$ feet.
Step2: Use the arc - length formula
The formula for the length of an arc $s$ of a circle with radius $r$ and central angle $\theta$ (in radians) is $s = r\theta$. First, convert the angle from degrees to radians. We know that $\theta=27^{\circ}$, and to convert to radians, use the conversion factor $\theta_{rad}=\theta_{deg}\times\frac{\pi}{180}$. So $\theta = 27\times\frac{\pi}{180}=\frac{3\pi}{20}$ radians. Then, substitute $r = 15$ and $\theta=\frac{3\pi}{20}$ into the arc - length formula: $s=15\times\frac{3\pi}{20}=\frac{9\pi}{4}\approx\frac{9\times 3.14}{4}=\frac{28.26}{4}=7.065$.
Step3: Round the answer
Rounding $7.065$ to one decimal place gives $7.1$.
Answer:
$7.1$
