The first time you find the area use 3.14 for pi. For the second attempt, leave the answer "in terms of pi." Explain all steps. Describe which way you would prefer to show your answer.

Leaving in terms of pi would be better because that would be the exact answer.

Value obtained using 3.14 would be an approximate answer

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
