Question

How many metres of canvas 1.25 m wide will be needed to make a conical tent whose base radius is 17.5 m and height 6 m?

Answer 1

Answer:

Step-by-step explanation:

Hey dude!!

Given :

Radius of cone (r)= 17.5 m

Height of cone(h) = 6 m

Slant height of cone(l) = √r²+h²

l = √6²+17.5²

l = √36 + 306.25 = √342.25

l= √342.25 = 18.5 m

Curved surface area of cone = πrl

= 22/7× 17.5 × 18.5

= 22× 2.5 ×18.5= 1017.5

Curved surface area of cone =1017.5 m²

Width of Canvas= 1.25 m

Length of Canvas required = C.S.A of Canvas / width of canvas

Length of Canvas required =1017.5/1.25 = 814 m

Length of Canvas required =814 m
