The
conical tent with radius 7m
and slant height 12m. is to be
made How many metals of 2 m
wide tarupulin will
be required ?​

Answer 1

Answer:

PLS MARK ME AS A BRAIN LIST

Step-by-step explanation:

Tarpaulin is the curved surface area of tent

The height of tent h=8m

And radius of tent r=6m

Then slant height of tent l=

r

2

+h

2

=

(6)

2

+(8)

2

=

36+64

=

100

=10

Curved surface area of tent =3.14×6×10=188.4m

2

Area of tarpaulin material = area of tent

length×breadth=Curved surface area of tent

lenght×3=188.4

⇒Length=

3

188.4

=62.8m

The wastes in tarpaulin =20cm=0.2m

Then length of tarpaulin =62.8+0.2=63m
