Answer 2

Answer:

TOTAL SURFACE AREA OF CYLINDER = 429 SQUARE CM.

Step-by-step explanation:

$h = 16 \: cm \\ \\ r = \frac{7}{2} \: cm \: \\ \\ tsa = 2\pi \times r(r + h) \\ \\ = 2 \times \frac{22}{7} ( \frac{7}{2} )( \frac{7}{2} + 16) \\ \\ = 22( \frac{32 + 7}{2} ) \\ \\ = 11 \times 39 \\ \\ = 429 \: {cm}^{2} .$
