Answer:

Let the radius of the base be r meters.

Then, the circumference:

2πr=44 m.

⟹ r=

44

=

2×22

44×7

=7m.

Let the slant height be l meters.

Then,

l=

h

2

+r

=

7

2

+24

2

=

625

=25m.

Now, Surface area = πrl=

7

22

×7×25=550m

2

.

∴ Area of canvas required =550 m

2

.

Given that width of the canvas is 2 m.

Therefore, Length of canvas required =

2

550

=275m.
