Question

Anindita has a pieace of pipe of canvas whose area is 551cm2 she used it to have a conical tent with the base radius of 7 m assuming that all the stiching margins and the wastage incurred while cutting amount to 1 m2 find the slant height of the conical tent

Answer 1

HEY MATE !!!!

let the tent have radius r = 7 m

let slant height = l m

let height = h m

area of Canvas =

area of Canvas =area available for making tent + wastage

$551 {m}^{2} = \\ area \: available \: \\ for \: making \: tent \: + 1 {m}^{2}$

area area available for making tent=

CSA of conical tent

550 =

$550 = \pi \: r \: l$

$550 = \frac{22}{7} \times 7 \times l$

$550 = 22 \times 1 \times l$

$l = \frac{550}{22} \\ l = 25m$

thus the slant height l= 25m

HOPE YOU'VE FOUND IT IMFORMATIVE !!!

PLEASE MARK AS BRAINLIEST!

THANKS!!
