Question

Jose is skiing on a circular ski trail that has a radius of 0.9 km. Jose starts at the 3-o'clock position and travels 2.65 km in the counter-clockwise direction. How many radians does Jose sweep out

Answer 1

2.94 rads

Explanation:

The number of radians that Jose sweeps out equals to the ratio of the chord length, which is the distance he travels in km, to the radius of the circular track, which is 0.9 km

= 2.65 / 0.9 = 2.94 rads

So Jose sweeps an angle of 2.94 radians
