Odpowiedź:
a) [tex]P_{c} = \pi * (\frac{d}{2})^{2} + \pi d*h = \pi * (\frac{6}{2})^{2} + \pi * 6 * 8 = 9\pi + 48\pi = 57\pi\ cm[/tex]
[tex]V = \pi (\frac{d}{2})^{2} * h = \pi * (\frac{6}{2})^2}*8 = 9 * 8 = 72\pi\ cm[/tex]
b) [tex]P_{c} = \pi r^{2} + 2\pi r*h = \pi * 4^{2} + 2\pi * 4*5 = 16\pi + 40\pi = 56\pi\ cm[/tex]
[tex]V = \pi r^{2} * h = \pi * 4^{2}*8 = 128\pi\ cm[/tex]
