Question : 36 of 150

Marks: +1, -0

The radius of the base of a conical tent is 16 metre. If

427{3/7}

sq. metre canvas is required to construct the tent, then find the slant height of the tent. (take π =

22 /7

)

Solution:

C.S.A of cone = πrl
∴

{ 22 } /{ 7 } × 16 × l = { 2992 }/ { 7 } 22 × 16 × l = 2992

l = { 2992 }/ { 22 × 16 } = 8.5 { m }
