Q. The radius of a quarter circle is

3\,\text{centimeters}

. What is the quarter circle's perimeter?

\newline

Use

\pi \approx 3.14

and round your answer to the nearest hundredth.

\newline

____ centimeters

Calculate Circumference: Calculate the circumference of the full circle using the formula $C = 2\pi r$ . $\newline$ Circumference $= 2 \times 3.14 \times 3$ $\newline$ $= 18.84$ cm
Find Quarter Circle Perimeter: Since we need the perimeter of a quarter circle, divide the full circumference by $4$ and add the diameter for the straight edges. $\newline$ Quarter circle perimeter $= \frac{18.84}{4} + 2 \times 3$ $\newline$ $= 4.71 + 6$ $\newline$ $= 10.71$ cm
