Question

6. The base of a conical tent is 19.2 metres in diameter and the height of its vertex is 2.8 metres. The area of the canvas required to put up such a tent (in square metres) (taking = ) is nearly.

Answer 1

Answer:

301.71 m^(2)

Step-by-step explanation:

Area = CSA of cone = $\pi rl$

r = 19.2/2 = 9.6

l = $\sqrt{9.6^(2) + 2.8^(2)} = \sqrt(100)$ = 10m

CSA = $10*9.6*\frac{22}{7}$

= 301.71 (approx.)
