Soltution:

Given h=3m, d=105m,

$r = \frac{105}{2} = 52.5m, l = 5m$

$Curved surface area of cylindrical = 2\pi rh = 2$ x $3.14$ x $52.5 x 3 = 989.1 sq.m.$

$Curved surface area of cone = \pi r l = 3.14$ x $52.5 $x $5 = 824.25sq.m.$

Area of total canvas required = 989.1 + 824.25

$= 1813.35 sq.m$
