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 π . round to the nearest meter. 10 m 21 m 102 m 204 m

21 m

Step-by-step explanation:

A sidewalk around a circular park covers a distance of 65 meters which means its the circumference of the circular park.

We know the formula for the circumference of a circle so we can write it as:

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.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
