Question

what is the formula of tsa of the cylinder

Answer 1

Hope u like my answer
======================
Total surface area (T. S. A) of cylinder

= Curved surface Area + 2× Area of Base

_________________________

=> Curved surface Area (C. S. A)
= $2\pi r \times h = \bf \: 2\pi rh$

=> Area of Base (A. B.) =$\pi {r}^{2} = \bf \: \pi {r}^{2}$

____________________

=> Total surface Area (T. S. A)

= (C. S. A.) + 2× (A. B.)

$= 2\pi rh \: + \: 2\pi {r}^{2} \\ \\ = \bf \underline{ \: 2\pi r(r + h) \: } \: \: unit ^{2}$

Answer 2

HERE IS YOUR ANSWER BUDDY,
____________________________________

The total surface area of the cylinder is 2π(r+h) where r = radius h = height
