​

Answer 1

Answer:

Slant height = 15m

Rupees = ₹7912.8

Step-by-step explanation:

The height(h) of the tent = 9m

Its base diameter = 24 m.

Radius = diameter/2

           = 24/2 = 12m

Slant height = $l$ = $\sqrt{height^2 + radius^2}$

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

                         = $\sqrt{9^2 + 12^2}$

                         = 15 m

Surface area of tent = $\pi rl$

                                 = $3.14$ x $12$ x $15$

                                 = $565.2m^2$

Cost of 1 sq. m.= Rs. 14

Cost of $565.2m^2$ = $14 * 565.2$ = ₹7912.8  

Thus the required cost = ₹7912.8
