Question

a conical tent is to accommodate 11 persons each person must have 4 meter square of space on the ground and 20 meter cube of air to breath. find the height of cone

Answer 1

Please mark as brainliest answer

As each person needs 4 sq.m space on ground

So 11 person will need 44 sq.m space on the ground.

Therefore,

Area of ground = 44sq.m

πr = 44sq.m

r = 44/π .......(1)

and each person needs 20cu.m of air

So 11 persons will need 220 cu .m of air

Therefore volume of tent = 220 cu.m

1/3πr h = 220cu.m

(1/3*π)*(44/π)*h = 220 ( from 1 )

1/3*44*h = 220

h = 220*3 / 44

h = 5*3

h = 15 cm

Answer 2

Answer:

Hey Mate..

Step-by-step explanation:

As each person needs 4 sq.m space on ground

So 11 person will need 44 sq.m space on the ground.

Therefore,

Area of ground = 44sq.m

πr = 44sq.m

r = 44/π .......(1)

and each person needs 20cu.m of air

So 11 persons will need 220 cu .m of air

Therefore volume of tent = 220 cu.m

1/3πr h = 220cu.m

(1/3*π)*(44/π)*h = 220 ( from 1 )

1/3*44*h = 220

h = 220*3 / 44

h = 5*3

h = 15 cm
