Answer

For constructing a pie diagram, it is necessary to convert the percentage into angles of different degree. This conversion is shown below:
Commodity Group Export (in %) Degree of Angles
Agriculture 17.3 $\frac{17.3}{100}\times360^\circ=62.28^\circ$
Minerals 2.6 $\frac{2.6}{100}\times360^\circ=9.36^\circ$
Manufactured goods 77.8 $\frac{77.8}{100}\times360^\circ=280.08^\circ$
Petroleum products 0.3 $\frac{0.3}{100}\times360^\circ=1.08^\circ$
Others 2.0 $\frac{2.0}{100}\times360^\circ=7.2^\circ$
Total 100 $360^\circ$
A pie diagram showing percentage of exports of given data is shown below:
