Question

How many square meters of canvas is required for a conical tent whose height is 3.5 m and radius base is 12 m

Answer 1

Answer:

We know that,

l² = r² + h²

l² = 12² + 3.5²

l² = 156.25

l = √156.25 = 12.5m .

Now,

Lateral surface Area = π rl = 3.14 ( 12.5)( 12 ) = 471 m²

Therefore, Required length of canvas = 471m²
