The total surface area of the tent shown in the figure is ..​

Answer 1

$2\pi \: rh + \pi \: rl \:$

CSA of cylinder +CSA of cone

Answer 2

Total surface area of tent = $2\pi rh + \pi rl$

Step-by-step explanation:

here,

the tent is in the shape of a cylinder having a conical top

l is the slant height

h is the height of the cylinder

r is the radius of the cylinder and cone

curved surface area of the cylinder = $2\pi rh$

curved surface area of the cone = $\pi rl$

then,

total curved surface area of the tent = curved surface area of the cylinder + curved surface area of the cone

=  $2\pi rh$ +  $\pi rl$

hence ,

Total surface area of tent = $2\pi rh + \pi rl$
