Answer:
Rs 2307.88
Step-by-step explanation:
Diameter =84 m, Radius =42 m
Outer radius =42+3.5 m =45.5 m
Outer area from center = πR^2
=3.14×(45.5)^2
=6500.58m^2
Inner area = πr^2 =3.14×42×42
=5538.96m^2
Area of round = (6500.58−5538.96)m^2=961.62m^2
Cost of construction = Rs. 2.40 per m^2
∴ cost of construction = Rs. 2.40×961.62
=Rs.2307.88.
