Answer:
Let the radius of the base be r meters Then
2
πr
= 44
or
r=
2π
44
=
2 × 2 2
4 4 × 7
=
7m
Let the slant height be l meters Then
l=
2
h 2
=
2
7 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
