If the radius of a circle is 10 feet, how long is the arc subtended by an angle measuring 81°?

1 answer:

If the angle is mesure in RADIANS then the arc is given by r. So first convert 81 degrees to radians, then multiply by r which is 10 x 81=810

<h2>Length of track is 168 meter</h2>

Step-by-step explanation:

Let l be the length of track.

Running speed = 4 m/s

Jogging speed = 2 m/s

Total time taken = 2 minutes 6 seconds. = 126 seconds

That is

$\frac{l}{4}+\frac{l}{2}=126\\\\0.75l=126\\\\l=168m$

Length of track is 168 meter
