Asidewalk around a circular park covers a distance of 65 meters. a new sidewalk is being constructed across the park through its center. about how long will the new sidewalk be? use 3.14 for π. round to the nearest meter.

21 m

Step-by-step explanation:

Circumference of circular park = 2πr

65 = 2πr

Solve this to find r:

65 = 2 x 3.14 x r

r = 65 / 6.28

r = 10.35

Now to find the find the distance of the new sidewalk, multiply r with 2 (to get the diameter):

2 x 10.35 = 20.7 ≈ 21 m

Therefore, the distance of new side walk, rounded to the nearest meter, is 21 m.

b is the answer that makes most sense

step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
