Question

In a circle there are 80 radii. What is the angle between the two consecutive radii?

Answer 1

Solution :-

The total circle is of 360 °

There are 80 radii, so the angle b/w 2 consecutive radii = 360°/80° = 4.5°

Answer 2

Given : In a circle there are 80 radii.

To Find :  the angle between the two consecutive radii?

Solution:

Central angle is 360°

If there are n radii

Then angle between the two consecutive radii  = 360°/n

there are 80 radii

=> n = 80

Hence angle between the two consecutive radii  = 360°/80

= 4.5°
