Question

a 3 m wide road runs around a circular park whose circumference is 132 m.Find the cost of fencing the outer boundary of the road at the rate of Rs.10per m​

Answer 1

Answer:

2×π×x

Let x be radius of inner circle. Then given circumference=132m

Equate with formula to get x =10. 5 m and add 3m to get outer radius and put in formulae

2×π×x

to get circumference 88.4m and multiply with 10rs to get cost of boundary 844rs
