Question

· A circus pandal is 240 m in radius and its height is 100 m.
Then the length of the cloth used to make the pandal when
width of the cloth is 100 pie m
​

Answer 1

Answer:

The area of cloth required to make the conical pandal would be equal to the curved surface area of the cone. It is given that the vertical height 'h' = 100 m and base radius 'r' = 240 m. Hence the slant height of the given cone is 260 m.

Answer 2

Answer:

Step-by-step explanation:

Here,

h=100m and r=240m.

We know,

l=

r

​

l=

​

l=

57600+10000

​

l=

67600

​

l=260m.

Curved surface area =πrl

=π×240×260

=62400πm

.

We know, Area of rectangle = length × breadth.

∴ Length of the canvas required

=

 =624m.

Hence, the length of the cloth that is required is 624m.
