Question

The following table shows the number of medals won in the 2008 Olympics for swimming by the top five countries. Country Number of Medals USA 31 Australia 20 Great Britain 6 China 6 France 6 How many degrees will the USA section be in a circle graph? 31° 45° 162° 184°

Answer 1

Answer:

Of the total 31 + 20 + 6 + 6 + 6 = 69 medals, the USA won 31 of them. 31/69 as a percentage is about 45%. Since there are 360° in a full circle, 45% of that is 0.45 * 360 = 162°.
