The Campagnolo Hyperon Ultra Two carbon wheel has 11 spokes

The Campagnolo Hyperon Ultra Two carbon wheel has 11 spokes evenly distributed around the rim of the wheel. What is the measure, in radians, of the central angle formed by adjacent pairs of spokes? rad

Solution

Total angle around the center = 360

And with 11 spokes total number of angles would be 11.

(imagine the no. of angles between 2 spoke are 2, between 3 spokes the angles are 3 and so on..)

Since the spokes are evenly distributed -

Angle between any 2 spokes = 2/11 radians = 0.57 radians = 32.73 degree
