$1kolumna$  

$d=2\cdot 5=10cm$  

$P_k=\pi \cdot 5^2=25\pi c{m}^2$   

$P_p=4\cdot \pi \cdot 5^2=4\cdot 25\pi =100\pi c{m}^2$  

$V=\frac{4}{3}\cdot \pi \cdot 5^3=$   $\frac{500\pi }{3}c{m}^3$  

 

 

$2kolumna$  

$169\pi =\pi r^2\Rightarrow 169=r^2\Rightarrow r=\sqrt{169}=13cm$  

$d=2\cdot 13=26cm$   

$P_p=4\cdot 169\pi =676\pi c{m}^2$   

$V=\frac{4}{3}\cdot \pi \cdot {13}^3=$   $\frac{8788\pi }{3}c{m}^3$  

 

 

$3kolumna$  

$\frac{4}{3}\cdot \pi \cdot r^3=36000\pi \Rightarrow \frac{4}{3}{r}^3=36000\Rightarrow r^3=36000\cdot \frac{3}{4}=$   $27000\Rightarrow r=30cm$  

$d=2\cdot 30=60cm$  

$P_k=\pi \cdot {30}^2=900\pi c{m}^2$  

$P_p=4\cdot 900\pi =3600\pi c{m}^2$  

 

 

$4kolumna$  

$4\pi r^2=2500\pi \Rightarrow 4r^2=2500\Rightarrow r^2=625\Rightarrow r=\sqrt{625}=25cm$  

$d=2\cdot 25=50cm$  

$P_k=\pi \cdot {25}^2=625\pi c{m}^2$  

$V=\frac{4}{3}\cdot \pi \cdot {25}^3=$   $\frac{62500\pi }{3}c{m}^3$
