Well

Rope with a bucket is fixed on the shaft with the wheel. The shaft has a diameter 50 cm. How many meters will drop bucket when the wheels turn 15 times?

Correct answer:

x =  23.6 m

Step-by-step explanation:

$$\begin{gathered} D=50\mathrm{/}100=0.5m \\ x=15\cdot o=15\cdot \pi D=15\cdot \pi \cdot 0.5 \\ x=23.6\text{ m} \end{gathered}$$
