Roller coverage area

The roller on the tennis court has a diameter of 60 cm and is 1.2 m wide. What area will the roller cover in one turn? They rounded to one decimal place.

Final Answer:

P =  2.3 m²

Step-by-step explanation:

$$\begin{gathered} D=60\text{cm}\to \text{m}=60:100\text{m}=0.6\text{m} \\ h=1.2\text{m} \\ P=\pi \cdot D\cdot h=3.1416\cdot 0.6\cdot 1.2=2.3{\text{m}}^2 \end{gathered}$$
