Question

Whta eill be the width of the following circuoar race track with inner diameter 10 cm and diameter 14 cm

Answer 1

Answer:

2 cm

Step-by-step explanation:

Let,

The centre of the inner circle = Centre of the outer circle.

Diameter of outer circle = 14 cm

Radius ,, ,, ,, = ( 14 / 2) cm = 7 cm           [∵ Radius * 2 = Diameter]

Diameter ,, inner ,, = 10 cm

Radius ,, ,, ,, = ( 10 / 2) cm = 5 cm

∴ Width of the race track = ( 7 - 5 ) cm

                                          = 2 cm
