Perimeter 31761

Mr. Marek wants to build a circular pond in his garden. He wishes the perimeter of the pond in meters and the area in square meters to be expressed in the same numbers. What is the radius of the pond?

Correct answer:

r =  2 m

Step-by-step explanation:

$$\begin{gathered} o=S \\ 2\pi r=\pi r^2 \\ r=2=2\text{m} \\ \text{ Verifying Solution: } \\ o=2\pi \cdot r=2\cdot 3.1416\cdot 2\doteq 12.5664\text{m} \\ S=\pi \cdot r^2=3.1416\cdot 2^2\doteq 12.5664{\text{m}}^2 \end{gathered}$$
