Question

a circular track 3.5m wide runs inside a circular garden of 56m radius. find cost of leveling track at 5 per sq. m

Answer 1

Answer:

Rs 5967.5

Step-by-step explanation:

Area of the circular field with radius 56m = 22/7*56*56= 9856 m^2

area of the circular field excluding the circular track= 22/7*52.5*52.5= 8662.5 m^2

now are of the circular track = area of the circular field- area of the circular field excluding the circular track

=9856-8662.5= 1193.5

cost of leveling track at 5 per sq. m= 1193.5*5=Rs 5967.5
