There is a circular track with out radius `10 . 5m` and inner radius `7 m` (a) the cost of levelling the track at rupees `24` per metre square

The inner and outer radii of a circular track area respectively 21 m and 28 m. The cost of levelling the track at ₹ 5 per sq m is

The outer circumference of a circular race-track is 528 m. The track is everywhere 14 m wide. Calculate the cost of levelling the track at the rate of 50 paise per square metre (U s e\ \ pi=22//7) .

The inner and outer radii of a circular track are respectively 21 m and 28 m. The cost of gravevelling the track at Rs. 5 per sq m is

The outer circumference of a circular race-track is 528 metre. The track is everywhere 14 metre wide. Cost of levelling the track at the rate of Rs. 10 per sq. metre 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

A rectangular ground is 90 m long and 32 m broad. In the middle of the ground there is a circular tank of radius 14 metres. Find the cost of turfing the remaining portion at the rate of Rs. 50 per square metre.

The inner circumference of a circular track is 220 m and the width of the track is 7 m. Calculate the cost of putting up a fence along the outer circle of the track at the rate of Rs. 50 per m.
