Question

a concial tent is 10 high and the radius of it's base is 24m.find the slant height of the tent and cost of the canvas required to make the tent if the cost of l m canvas is rupees 70​

Answer 1

Step-by-step explanation

Height -10m

Radius -24m

Applying phythagoras theorm

24*24+10*10=l^2

l-slant height

676=l^2

l=26

Then Find csa of cone πrl =22/7*24*26(3.14 if mentioned)

Multiply this csa which we get with 70

(We don't consider total surface area because canvas is open from base )

Hope it helps

Answer 2

Answer:

slant height= 10x10 + 24x24

100 + 576

676

26 ans

Step-by-step explanation:

2pie r h +pie r l

pie r (2h + l)

22/7 x 24 (2x10+26)

22/7 x 24 x 46

24288/7

3469.71 m sq

if 1 m canvas is 70 then 3469.71 x70= 242879.7 ans....
