{ \boxed{ \red{ \tt{Solution:}}}}

 \tt \: 2\pi r  = 220

 \tt \: 2  \times  \frac{22}{7}  \times  r = 220

 \tt \: r=220  \times  \frac{7}{44}

 \tt \: r = 35 cm

Now, we have Radius = 35 cm & Height = 105 cm. Therefore total surface area -

{ \boxed{ \tt{TSA \:  of \:  Cylinder = 2πr (h+r) }}}

 \tt \: TSA = 2  \times  \frac{22}{7}  \times  35 (105 + 35 ) cm²

 \tt \: TSA =  \frac{44}{7}  \times  35 (140) cm²

 \tt \: TSA = 44  \times  5  \times  140 cm²

 \tt \: TSA = 30,800 cm²

Hence, the total surface area of cylinder is 30,800 cm².

Curved Surface area of cylinder = \tt \: 2\pi rh

Volume of cylinder =  \tt \: \pi  {r}^{2} h
