r=105/2

H=3

h=53

Tsa of canvas used = csa of cylinder + csa of cone

Put the values u will get the answer.

Thankyou..:)

in the cylinder

height = 3 m

radius = 105/2 m

CSA of the cylinder = 2πr(r+h)

in the cone

slant height = 53 m

radius = 105/2 m

CSA of the cone = πrl

TSA of the tent = CSA of the cylinder + CSA of the cone

= 2πr(r+h) +πrl

= πr[2(55.5)+53]

= πr[111+53]

= πr[164]

= 22/7 ×105 164

= 2460 cm²

it need the 2460 cm² cloth
