In a divided circle illustrating the world's export of crude oil, if the section taken up by the share of a certain country measures 72°, then the share of that country's export expressed as a percentage can be calculated as follows: - A full circle is 360°. - The share of the country is 72°, which is a fifth of the circle because 5 x 72° = 360°. - Therefore, the share of the country's export as a percentage is 20% because 1/5 = 0.2 or 20%. Therefore, the answer is 20. The country's share of the world's export of crude oil, as illustrated in the divided circle, is 20%.
