Question

11. A conical tent contains 103.488 m of air. If the radius of the base of the tent is 4.2 m,
find the amount of canvas needed to make this tent.
​

Answer 1

Answer:

amount of tent =72126

Step-by-step explanation:

Area = 2^rh

2 * 22/7*4.2*h

h=26.4

Area = 2 ^rh

=2*22/7*0.6*26.4

= 696.96

Hence

Amount = area * conical tent contains air

= 696.96 * 103.488

= 72126 approx
