Question

The diameter and the slant height of a conical tent are 16 m and 5.6 m, respectively. What length of cloth having width 4m is needed to make the tent?

A 35.2 m Correct Answer Incorrect Answer
B 32.5 m Correct Answer Incorrect Answer
C 32 m Correct Answer Incorrect Answer
D 35 m Correct Answer Incorrect Answer

Solution

⇒ Surface area of the conical tent = π × (Slant Height) × (Diameter/2) => (22/7) × 5.6 × (16/2) = 140.8 m ⇒ Total area of cloth = 140.8 ⇒ Length × Breadth = 140.8 ⇒ Length × 4 = 140.8 ⇒ Length = 35.2 m
