Answer:
Let h be the height of the conical tent
r be the radius of its base B be the width of the canvas
Circumference of base=44
2×pie×r=44
R=
44
44∗7
R=7m
l=
9∗7+44∗44
=5
Area of canvas =csa of cone
L×B=pie×r×l
L=
7×2
22×5×7
=55m
Thus the length of canvas used 55m

Circumference of base=44
2× pie× r= 44
R=
44
44∗7
R= 7m
l=
9∗7+44∗44
=
5
Area of canvas = csa of cone
L× B= pie× r× l
L=
7×2
22×5×7
= 55m
Thus the length of canvas used 55m
