Question

A conical tent is 10m high and the radius of its

base is 24m. Find the

(i) Slant height of the tent

(ii) Cost of the canvas required to make the tent, if

cost of 1m2

is Rs.50​

Answer 1

Answer:

Step-by-step explanation:

h=10 m , r=24m

(i) slant height of tent(l) =>

                      l² = r²+h²

                    l² = 576 + 100

                     l² = 676

                      l=26 m

(ii)cost of canvas required to make the tent=>

                              surface area of tent = πrl

                                                                   =( 22/7) * 10*26

                                                                   =817.14 m²(approx)

cost of canvas= 50 * 817.14

                      =40,857 Rs (approx)
