Question

write about the life of early men ?​

Answer 1

Answer:

Many years ago, early humans lived in the jungle and were afraid of bigger and stronger animals. They did not know how to build houses. So, they spent their time on the trees or hid themselves behind the bushes. But all this could not help them to save themselves from wild animals and harsh climatic conditions.

Given:-

Radius of the cloth is 240m.

Height of the cloth is 100m.

Width of the cloth is 100π.

To Find:-

Length of the cloth.

Solution:-

We know that to find the CSA of the cone we need it's length.

\large\boxed{\bf{ \implies length_{cone} = \sqrt{ {radius}^{2} + {height}^{2} } }}

⟹length

cone

=

radius

2

+height

2

Now on substituting values we get:-

\large\underline{\sf{ \longmapsto length = \sqrt{ {(240m)}^{2} + {(100m)}^{2} } }}

⟼length=

(240m)

2

+(100m)

2

\large\underline{\sf{ \longmapsto length_{cone} = \sqrt{ {57600} {m}^{2} + 10000} {m}^{2} }}

⟼length

cone

=

57600m

2

+10000

m

2

\large\underline{\sf{ \longmapsto length_{cone} = 260m }}

⟼length

cone

=260m

Now the curves surface area of cone is equal to the area of rectangle.

\large\underline{\sf{ \longmapsto length \times breadth = \pi rl}}

⟼length×breadth=πrl

\large\underline{\sf{ \longmapsto length \times 100\pi m= \pi \times 240m \times 260m}}

⟼length×100πm=π×240m×260m

\large{\sf{ \longmapsto length = \frac{\pi \times 240m \times 260m}{100m \times \pi} }}⟼length=

100m×π

π×240m×260m

\large{\sf{ \longmapsto \frac{ \cancel{\pi \times 240m \times 260m}}{ \cancel{\pi \times 100m}} }}⟼

π×100m

π×240m×260m

\large\underline{\sf{ \longmapsto length = 24m \times 26}}

⟼length=24m×26

\large\boxed{\sf{ \implies length = 624m}}

⟹length=624m
