Question

army made 50 conical tents of height 10m and base radius 24m .If the cost of canvas is ₹140/m.sq then find the total cost of making the tents

Answer 1

Total cost of the tent is Rs.840,000

Answer 2

Answer:

Rs. 13715520

Step-by-step explanation:

Height of conical tent = 10 m

Radius of conical tent = 24 m

Curved surface area of tent = $\pi r \times \sqrt{h^2+r^2}$

Substitute the values in the formula

Curved surface area of tent = $3.14 \times 24 \times \sqrt{10^2+24^2}$

                                              = $1959.36 m^2$

Surface area of 1 tent = 1959.36 sq.m.

Surface area of 50 tents =$1959.36 \times 50=97968$ sq.m.

Cost of 1 sq.m. of canvas = Rs.140

Cost of 97968 sq.m. of canvas = $97968 \times 140=13715520$

Hence  the total cost of making the tents is Rs. 13715520
