Question

a circular park has radius 8m has a path 2m wide find the cost of metalling the path at rate of 600msq​

Answer 1

Answer:

Rs.1628/-

Step-by-step explanation:

Area of big circle= π*r²

=22/7*8*8=201.14 m

Area of small circle= π*r²

=22/7*(8-2)²=22/7*36=113.14 m

Area of the path=Area of big circle-Area of small circle

=201.14-113.14=88 m

Cost of Paving= 88*18.5

=Rs.1628/-
