Answer» Applying Pythagors' theorem,slant height, l² = r² +h²⇒ l² = 3² +4²⇒l² =25⇒slant height = 5mnow, curved surface area =π× r×l = 3.14×3×5 = 47.1 m²now, 10% extra material is required for stitching and wastage = 0.1×47.1=4.71 m²total area = 47.1 +4.71 =51.81 m²now, L×B = 51.81⇒Length ,L = 51.81/4.5 = 11.51 m |
