Odpowiedź:
R=1
P= 4*
[tex] p = 4 \times \pi \times {r}^{2} \\ p = 4 \times \pi \times {1}^{2} \\ p = 4\pi[/tex]
[tex]v = \frac{4}{3} \times \pi \times {r}^{3} \\ v = \frac{4}{3} \pi[/tex]
[tex]p = 16\pi \\ 16\pi = 4 \times \pi \times {r}^{2} \: \: podzielic \: obustronnie \: przez \: 4\pi \\ 4 = {r}^{2} \: \: \: \sqrt{?} \\ r = 2[/tex]
