Question

a conical tent is 16m high and radius of base is 24cm Find the C.SA of the tent​

Answer 1

Explanation:

here,

height of a conical tent=16m

Diameter=24m

we know that ,

radius is half of the diameter .

radius=24/2

radius=12m.

slant height=?

NOW,

The canvas will be used on the curved surface area of conical tent.

Curved surface area of cone =πrl

=22/7×12×20

=22/7×240

=22×34.29

=754.38sq .cm

The cost of canvas required to make the tent at the rate of ₹210

754.38×210

=1,58,419.80₹

THEREFORE,

Answer 2

Answer:

12.05 m^2

Explanation:

CSA of a Cone = (pie)*r*l

l = slant height

r = radius

h = height of cone

l = root of ( r^2 + h^2)

l = root of ( .24^2 + 16^2)

l = root of ( 0.0576 + 256)

l = 16.002 m

Thus CSA = 3.14*0.24*16.002 = 12.05 m^2
