what is 1r0m? Write the data correctly.
wr have to find the inside distance and outside distance.
for the inside distance ,radius =140/2=70m
length of circumference=2pi×r =2×22/7×70=440m
Now,outside distance radius =70+7=77m
length of circumference=2pi×r=2×22/8×77=484m
Total length =440+484=924m
Cost=7×924=6468Rs.
