Question

quentin is designing a circular garden for the entrance to the high school. if the radius of the garden is 3 meters, how many meters of edging will quentin need to surround the garden? (use π = 3.14.) a. 6.14 meters b. 9.42 meters c. 18.84 meters d. 28.26 meters

Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius of the circle and $\pi\approx3.14$.

Step2: Substitute the given radius into the formula

Given $r = 3$ meters and $\pi=3.14$, we have $C=2\times3.14\times3$.
First, $2\times3 = 6$, then $6\times3.14=18.84$ meters.

Answer:

C. 18.84 meters
