Question

t the diameter of the circular path is 140 M around its on out the outside a path having the breadth of 7 M is constructed if the path has to be fencing from inside and outside at at the rate of 7 per metre find the total post

Answer 1

inside-rupees3080
outside-rupees3388

Answer 2

diameter of inside circle=140
r=70
perimeter of inside circle =2πr
=2×22/7×70
=440m

width of path= 7m
radius of outer circle = 70+7=77

perimeter of outer circle = 2πr
=2×22/7×77
=484m

total perimeter = (440+484)m
=924
cost of fencing per m= 7
cost of fencing for 924m = 924×7
=Rs 6468

hope it helps uh
