**What length of tarpaulin 3 m wide will be required to make conical tent of height 8 m and base radius 6 m? Assume that the extra length of material that will be required for stitching margins and wastage in cutting is approximately 20 cm (Use ).**

**Solution:**

Breadth of tarpaulin = **3 m**

Height of conical tent **m**

Radius of the base of conical tent **m**

Slant height of conical tent **m**

**According to given condition, we have**

Length of tarpaulin breadth of tarpaulin = Curved Surface area of conical tent

length of tarpaulin

length of tarpaulin

Length of Tarpaulin

Length of Tarpaulin **m**

Extra length of material that will be required for stitching margins and wastage in cutting is=**20 cm**

**Length of tarpaulin required =62.8 m +20 cm=62.8 m+0.2 m=63 m**
