Q. The perimeter of a quarter circle is 10.7110.71 meters. What is the quarter circle's radius?\newline\newlineUse π3.14\pi \approx 3.14 and round your answer to the nearest hundredth.\newline____ meters
  1. Identify Formula: Identify the formula for the perimeter of a quarter circle, which includes the curved part and two radius lines. The formula for the full circle's circumference is 2πr2\pi r, so for a quarter circle, the curved part is 14×2πr=πr2\frac{1}{4} \times 2\pi r = \frac{\pi r}{2}. Adding two radius lines, the total perimeter PP is πr2+2r\frac{\pi r}{2} + 2r.
  2. Set Up Equation: Set up the equation with the given perimeter:\newlineπr2+2r=10.71 \frac{\pi r}{2} + 2r = 10.71 \newlineSubstitute π3.14\pi \approx 3.14 into the equation:\newline3.14r2+2r=10.71 \frac{3.14r}{2} + 2r = 10.71
  3. Combine Like Terms: Combine like terms:\newline3.14r2+2r=10.71 \frac{3.14r}{2} + 2r = 10.71 \newline(3.142+2)r=10.71 \left(\frac{3.14}{2} + 2\right)r = 10.71 \newline(1.57+2)r=10.71 (1.57 + 2)r = 10.71 \newline3.57r=10.71 3.57r = 10.71
  4. Solve for r: Solve for rr:\newliner=10.713.57 r = \frac{10.71}{3.57} \newliner3.00 r \approx 3.00 meters
