Pool

The pool has the shape of a cylinder with a diameter of 4.6 m, and the presumed height is 130cm. The bucket fits 12l of water. How many buckets do you have to bring to fill this pool?

Correct answer:

n =  1801

Step-by-step explanation:

$$\begin{gathered} D=4.6\cdot 10=46 \\ h=130\mathrm{/}10=13 \\ r=D\mathrm{/}2=46\mathrm{/}2=23 \\ {V}_1=\pi \cdot r^2\cdot h=3.1416\cdot 23^2\cdot 13\doteq 21604.7327 \\ {V}_2=12 \\ n=\lceil V_1\mathrm{/}{V}_2\rceil =\lceil 21604.7327\mathrm{/}12\rceil =1801 \end{gathered}$$
