Answer:

T.S.A. of cylinder=

[tex]2\pi r(r + h) \\ \\ = 2 \times \frac{22}{7} \times 11(11 + 10) [/tex]

Wait a second

How 11 came as radius.

Reason:

As we know that diameter is 22 cm so radius is

[tex] \frac{22}{2} = 11 \\ [/tex]

So let's continue..

[tex] = 2 \times \frac{22}{7} \times 11(21) \\ \\ = 2 \times 22 \times 11(3) \\ \\ = 44 \times 11(3) \\ \\ = 484(3) \\ \\ = 1452 [/tex]

Ao answer is

[tex] {1452cm}^{2} [/tex]
