The inner circumference of the circular track is 440 m and the track is 14 m wide.Calculate the cost of levelling the track at the rate of 25 paise per sq. m.Also, find the cost of fencing the outer circle at the of Rs. 5 per m.[Use pi = 22/7]

Hi!
Here is the answer to your query.
 
Let the radius of inner circular track is r.
Given that the circumference of the inner circular track is 440 m
Width of the track is 14 m
Thus, the radius of the outer circle of the track, R = 70 m + 14 m = 84 m
 
 
Cost of leveling the track = 6776 × 25 paise = 6776 × Rs 0.25 paise = Rs 1694
 
Cheers!
