Answer:
Step-by-step explanation:given,
C of smaller circle=88m
width of path= 2m
circumference =88
2πr=88
r=88×7/2×22
=14m
r of bigger circle=14+2=16m
area of circular path =π(R^2-r^2)
=22/7(16×16-14×14)
=22/7(256-196)
=22/7×60cmsq.
cost of tilling=22/7×60×39
=rs 735.42
plz reply it's correct or not
