Answer 2

The cost of paving the path is Rs.392700

Step-by-step explanation:

Diameter of circular field = 175 m

Radius of circular field =$\frac{175}{2}=87.5 m$

.It is surrounded by a path 3.5m wide

Outer radius = 87.5+3.5=91 m

Area of path = Outer area - inner area

Area of path = $\pi R^2 - \pi r^2$

Area of path =$\frac{22}{7}(91^2-87.5^2)=1963.5 m^2$

Cost of paving 1 sq.m. = Rs.200

Cost of paving 1963.5 sq.m. =$200 \times 1963.5=392700$

Hence The cost of paving the path is Rs.392700
