QUESTION :

(1.) If length of a chord passing through the centre of the circle is 10cm , what is the radius of the circle ?

ANSWER :

→ Chord passing through the centre of the circle = 10 cm

→ Radius = Diameter / 2

→ Radius = 10 cm / 2 = 5 cm

Therefore, The radius of the circle is 5 cm

QUESTION :

(2.) What will be the width of the following circular race track with an inner diameter of 10cm and Outer diameter of 14 cm ?

ANSWER :

→ Diameter = 10 cm

→ Radius = 10 cm / 2 = 5 cm

→ Diameter = 14 cm

→ Radius = 14 / 2 = 7 cm

Therefore, the length of the Width = 7 - 5 = 2 cm
