Question

45. The radius of the base of a conical tent is 16 metre. If 427 sq. Metre canvas is required to construct the tent, then the slant height of the tent is

Answer 1

curved surface area of cone = πrl

427 sq.m= 22/7×16×l

l= 427×7/22×16

l = 8.491 m (approx)

Answer 2

Answer:

CSA of cone =πrl

427 3/7 = 22/7 ×16 ×l

2989/7 =22×16× l

2989/7 =l

7×22×16

2989/ =l

352

l= 8.491 m
