In a circle whose radius is 8 the length of the circle is 2 pi in the radians what is the measure of the central angle subtended by the arc?

we are given

radius is 8

length of arc is 2pi

now, we can use formula

where

theta is central angle

...........Answer

is this part of a question or something

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
