The circumference of the base of 20m high conical tent is 44m. Calculate the length of canvas used in making the tent if the width of the canvas is 2m. *

Answer 1

Answer:

Length = 220.55m

Step-by-step explanation:

Width of Canvas = 2m

Circumference = 44m

Height = 44m

2πr = 20m

πr = 10m

r = 70/22m

l = √h^2+r^2 = √1936+4900/484 = √941924/484 = 970.52/22 = 44.11m

Therefore, Slant Height = 44.11m

CSA Of Cone = Area of Canvas

πrl = Length*Width

22/7*70/22*44.11 = 2m*Length

67929.4/154 = 2m*Length

441.1 = 2m*Length

Length = 220.55m

Answer 2

Answer:

$\bold{Length = 220.55m}$

Width of Canvas = 2m

Circumference = 44m

Height = 44m

2πr = 20m

TIr = 10m

r = 70/22m

1 = √h^2+1^2=√1936+4900/484 = √941924/484 = 970.52/22 = 44.11m

Therefore, Slant Height = 44.11m

CSA Of Cone = Area of Canvas

Trl = Length*Width

22/7*70/22*44.11 = 2m*Length

67929.4/154 = 2m*Length

441.1 = 2m*Length

Length = 220.55m
