The inner and outer radius of a circular track are 56 m and 63m respectively. Find the area of the track

If the outer and the inner radii of a circular track are 7 m and 3.5 m respectively, then the area of the track is ________.

The inner and the outer radii of a circular track are 7 m and 14 m, respectively. Find the cost of levelling the track at the rate of rs. 100 per m^(2) . The following steps are involved in solving the above problem. Arrange them is sequential order (A) Area of circular track =pi(R^(2)-r^(2)) and given R = 14 m and r = 7 m (B) therefore "Area of circular track"=(22)/(7)(196-49) "(C) Area of the track "=(22)/(7)xx147=22xx21=154cm^(2) (D) "Cost of levelling the path "=462xx100="Rs."46,200
