Question

Represent number of satellites launched by isro from 2015 - 2019 with the help of piechart

Answer 1

Answer :

Year   Number of satellites launched

2015                           4

2016                           8

2017                           8

2018                           9

2019                           3

Total number of satellites launched

      = 4 + 8 + 8 + 9 + 3 = 32

Degrees of launching satellites

  2015 ⇒ 4/32 × 360° = 45°

  2016 ⇒ 8/32 × 360° = 90°

  2017 ⇒ 8/32 × 360° = 90°

  2018 ⇒ 9/32 × 360° = 101.25°

  2019 ⇒ 3/32 × 360° = 33.75°

Drawing of the pie-chart :

• Draw a circle using pencil compass

• Draw a line to make a radius

• Put the protractor on the circle taking radius as the base

• Draw each section division from the above chart by taking the previous section connector as the current base
