Answer 2

Answer:

$curved \:surface\: area = 616cm^{2}$

$total \:surface\ area = 924 cm^{2}$

$volume\:of\:the\:cylinder = \:2156 cm^{2}$

Step-by-step explanation:

h = 10cm

r = 7cm

NOW,

$l.S.A. \: of\: a\: cylinder = 2\pi rh\\= 2*\frac{22}{7} * 7 * 14\\= 44*10\\= 616cm^{2}$

NOW,

$TSA \: cylinder = 2\pi r(r+h) \\ \\= 2 * \frac{22}{7} * 7 (14+7)\\\\= 924cm^{2}$

$volume\:of\:the\:cylinder =\pi r^{2} h\\=\frac{22}{7} *7*7*14\\=2156cm^{2}$

Hope this answer helped you out, have a nice day
