Question

plss solve this quessss

Answer 1

i hope this is clear now

Answer 2

Let the outer radius be R=112 m(105+7) and the inner radius be r=105 m.
Therefore,area of the path=$\pi (R^{2} - r^{2} )$
                                         =1519$\pi$
Therefore,cost of paving the road=Rs.1519$\pi$*12.35
                                                     =Rs.58958.90(ans)

Have a nice day!
