πrl is a formula of CSA of cone
π mean pie and r is a radius and L is a slant height of a cone
Now Solve
CSA of cone = πrl
L is not present so we can find L
H
L square = H square + R square
L square = 8 square + 6 square
L square = 64+ 36
L square = 100
L = √100
L = 10
we can find CSA of cone
CSA of cone = πrl
= 3.14×6×10
= 188.4metersquare
we know that of canvas is a rectangle like structure . So,
Area of rectangle = Area of Canvas
Area of canvas = Length × Breadth
188.4 = Length × 3
Length = 188.4/3
= 62.8m
