Question

The circumference of a base of a 10m high conical tent is 44m Calculate the cost of canvas required to make the tent at rupees 15per ms​

Answer 1

Step-by-step explanation:

Circumference of base of tent = 44m

Therefore, 2πr = 44m

Hence , r = 7m

Now,

Height of conical tent = 10m

Its Slant Height =

$\sqrt{h^{2} + {r}^{2} }$

Therefore, Slant height =

$\sqrt{ {10}^{2} + {7}^{2} } = \sqrt{149} = 12.2m$

CSA of conical tent = πrl =

$3.14 \times 7 \times 12.2 = 268.15 \: {m}^{2}$

Cost of canvas required to make the tent at rupees 15per m² = 268.15 × 15 = ₹4022 (approx.)
