Given :-
- A conical tent is 15m high and the radius of its base is 20m.
To find :-
- Total cost required for making canvas
Solution :-
- Height of canvas = 15 m
- Radius of base = 20m
As we know that
→ Slant height = √(radius)² + (height)²
→ l = √(r)² + (h)²
→ l = √(20)² + (15)²
→ l = √400 + 225
→ l = √625
→ l = 25 cm
Now,
- Curved surface area of canvas = curved surface area cone
→ πrl
→ 22/7 × 20 × 25
→ 440/7 × 25
→ 11000/7 cm²
- The cost of the Canvas required to make the tent at the rate of ₹ 7 per m²
→ Total cost
→ 11000/7 × 7
→ Rs.11000
Hence,
- Total cost required for making canvas is Rs11000
