Find the length of canvas, 1.5m in width, is required to make a conical tent 14 m in diameter and 24 m in height. Given that `8(1)/(3)%` of the canvas is used in folds and stiching. Also, find the cost of canvas at the rate of Rs. 28 per metre.

Explanation

To solve the problem of finding the length of canvas required to make a conical tent and its cost, we will follow these steps:

### Step 1: Find the radius and height of the cone
- Given the diameter of the conical tent is 14 m, the radius \( r \) can be calculated as:
\[ r = \frac{\text{diameter}}{2} = \frac{14}{2} = 7 \text{ m} \]
- The height \( h \) of the cone is given as 24 m.
