Q3. Rehman is making a wheel using spokes. He wants to fix equal spokes in such a way that the angles between any pair of consecutive spokes are equal. Help him by completing the following table.
(iii) How many spokes would be needed, if the angle between a pair of consecutive spokes is ?
Number of spokes |
4 | 6 | 8 | 10 | 12 |
Angle between a pair of consecutive |
.... | .... | .... |
If the angle between a pair of consecutive spokes is then,
Number of spokes needed would be
Hence the required number of spokes for having 40 degrees of angle is 9.
