Question

The height of the tent is 9m. Its base diameter is 24 m. What is its slant height?find the cost of canvas cloth required if its costs 14 rupees per Sq m

Answer 1

if it costs rs14 per sq.m. - 1070758. ... l is here slant height hence area of clothes=22/7 x 12 x 15 hence cost of canvas clothes=area of canvas clothes x rate =22/7 x 12 x 15 x 14=7920 Rs.

Answer 2

Answer:

Slant height l=15

Rs.7912.8

Step-by-step explanation:

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

The height(h) of the tent is 9m

Its base diameter is 24 m.

Radius = 24/2 = 12

So, Slant height l=$\sqrt{9^2+12^2}$

Slant height l=15

Surface area of tent = $\pi r l$

                                  = $3.14 \times 12 \times 15$

                                  = $565.2 m^2$

Cost of 1 sq. m.= Rs. 14

Cost of 565.2 sq.m. = 14 * 565.2 =Rs.7912.8

Thus the cost is Rs.7912.8
