Question

what will be the width of the following circular race track with inner diameter 10 cm and outer diameter 14 cm​

Answer 1

Answer:

Given, inner diameter = 10cm => inner radius = 5cm

outer diameter = 14cm => outer radius = 7cm

From the question,

Width of circular track = Outer radius - Inner radius

Width = 7 - 5 = 2cm

Therefore, the circular race track is 2cm wide.

P.S., I think the units should've been metres instead of centimetres, but okay...
