Question

the conical tent of radius 7 meter and heght 24 meter is to be made. Find the cost of the 5 meter wide cloth required at the rate of rupees 50 per meter

Answer 1

Answer:

Rs 5280

Step-by-step explanation:

r = 7 m

h = 24 m

slant height (l) = ( 7 ^2 + 24^ 2) ^ 1/2

                       = 25 m

Its Area = Pi * r * l

             = 22 / 7 * 7 * 24

             = 528 m ^ 2

Cost = 528 / 5 * Rs 50

       = Rs 5280
