Study the given chart and answer the following question.

What is the central angle corresponding to the production steel by Kerala?

72°

Production of steel in kerala = 200

Total production of steel = 220 + 240 + 180 + 160 + 200 = 1000

Central angle corresponding to the production steel by Kerala

= \(\frac{200}{1000}\) × 360º

= \(\frac{1}{5}\) × 360º

= 72º
