Question 76

A circle has a diameter of 14 centimetres. Which statement about that circle is correct?

  1. Its radius is 3.5 centimetres.
  2. Its radius is 7 centimetres.Bonne réponse
  3. Its radius is 14 centimetres.
  4. Its radius is 28 centimetres.

Explication

The distance right across the circle is made of two equal pieces meeting at the centre, so each piece is 14 shared between two. Doubling to 28 travels in the wrong direction and would describe a circle four times as wide as the one given here.
