A circular track has a diameter of 127 m. Find the circumference of the track. Use 3.14 for pie​

398.982267

Step-by-step explanation:

C=πd

 C=π×127

C=127π

C=398.982267

398.78 meters

Step-by-step explanation:

Because the formula to find circumference is d*pi, we just plug in our number.

The circumference is 127pi

Then we plug in 3.14 for pi

That's 127 * 3.14

(You can ignore this next part, I just do it out so I can do it in my head) That's 381 + 12.7 + (1.27*4)

381 + 12.7 + (3.81 + 1.27)

381 + 12.7 + 5.08

398.78

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
