Question

The inner and outer circumference of the circle backing track R2 64 and 352 respectively find the the width of the racing track

Answer 1

Answer:

inner circumference = 264

outer circumference = 352

Let the inner radius be r

ATP

2×22/7 r = 264

=> r = 264 ×1/2 ×7/22

=> r = 42

inner radius = 42

Let the outer radius be R

ATP

2×22/7 R = 352

=> R = 352×1/2×7/22

=> R = 56

outer radius = 56

width = R-r = 56-42 = 14

answer :- 14
