Answer:

the length of cloth =135.05(approx.)

Explanation:

the length be x m and the width =1m

area of cloth required = x m

the height of cone =7 m

the bar radius of cone =5m

the curved surface area = (22*5*slant height) /7

x =  \frac{22}{7}  \times 5 \times  \sqrt{( {7}^{2}  +  {5}^{2})  }  \\ x =  \frac{22}{7}  \times 5 \times  \sqrt{74}  \\ x = 135.05(approx.)
