Question

what will be the cost of electrical wire used for single phase wiring (live, neutral &earth) along the boundary wall of the circular stadium of diameter 98? the rate of single core cable for live & neutral is rs 15per meter and the rate of earth wire is rs 5 per meter?

Answer 1

Hi ,

Let the diameter of the

circular stadium ( d ) = 98 m

Length of the boundary = circumstance of the

circle

P = πd

P = ( 22/7 ) × 98

P = 22 × 14

P = 308 m

Cost of single phase wiring

=( rate of single cable + rate of earth wire )P

= ( 15 + 5 ) × 308

= 20 × 308

= Rs 6160

I hope this helps you.
