Sangeetha Pulapaka

The angle of a full circle is 360^\circ

The sector representing Asia (purple) is bigger than half (50%), but less than three quarters (75%), so 60% is the best answer.

You can get a better estimate by measuring the angle for Asia with a protractor. It is about 215°

As a percent of 360°, this is 215/360 × 100% = 59.7%
