Answer:
The length of metal boundary is 9.42m and,
Cost of Boundary is ₹235.5
Step-by-step explanation:
From the question we can find the radius of metal boundary I. e. diameter/2
To find it's proper length, we can take it's circumference as it's length which is 2πR where R is the radius.
Radius = diameter/2
R = 3/2
So R=1.5m
Therefore length = 2πR
=2×3.14×1.5m
=9.42m
To find the cost we can say that for every one meter cost is ₹25 so for 9.42 m we get the cost as
9.42×25
that is 235.5 rupees.
