Detailed Solution

Given,
A circus tent is cylindrical to a height of 3 m and conical above it, with its base radius as 52.5 m and the slant height of the conical portion as 53 m.
We have to find the area of canvas.
Constructing the diagram,
Question Image

Applying the formula for curved surface area of the cylindrical portion:
Curved surface area of cylinder

= 2 π r h

Curved surface area of the cylindrical portion

= 2 × 227 × 52.5 × 3

=990m2
Applying the formula for the curved surface area of conical portion:
Curved surface area of cone

= π r l

Curved surface area of the cylindrical portion

= 227 × 52.5 × 53

=8745m2
So, total area of canvas required for making the tent:

= (8745 + 990) m 2 = 9735 m 2

Thus, the total area of canvas required for making the tent is

9735 m 2

.
Therefore, option 1 is correct.
