Q. The perimeter of a quarter circle is 7.14 inches. What is the quarter circle's radius?Use π≈3.14 and round your answer to the nearest hundredth.____ inches
Understand the problem: Step 1: Understand the problem.We need to find the radius of a quarter circle given its perimeter is 7.14 inches.
Use the formula: Step 2: Use the formula for the perimeter of a quarter circle.The perimeter of a quarter circle includes one-quarter of the circle's circumference plus the two radii. The formula is: Perimeter = (π⋅radius)/2+2⋅radius.
Set up the equation: Step 3: Set up the equation.7.14=23.14×radius+2×radius.
Simplify and solve: Step 4: Simplify and solve for radius.Combine like terms: 7.14=(1.57×radius)+2×radius,7.14=3.57×radius,radius=3.577.14,radius=2.00 inches.
