Answer» width of the canvas(L)=2m slant height=6.3m diameter =12m=> 2 × radius=12m=>radius(r)=6m therefore, area of canvas = curved surface of conical tent=>L × B=22/7 × rl=>L × 2=22/7 × 6 × 6.3=>L=59.4m It is given that, cost per 1 meter is Rs.12.50 therefore, cost of 59.4m cloth=Rs.12.50 × 59.4=Rs.742.50 |
