Area, SM-Bank 064 MC A circular pool is located in a square lawn, as shown below. The sides of the square lawn are 10 m in length. The pool has a radius of 3 m. The area of the lawn surrounding the pool, in square metres, is closest to \(59\) \(72\) \(81\) \(128\) Show Answers Only \(B\) Show Worked Solution \(\text{Area of square}\) \(=\text{side}^2\) \(=10^2\) \(=100\ \text{m}^2\) \(\text{Area of pool}\) \(=\pi r^2\) \(=\pi \times 3^2\) \(= 28.27\dots\ \text{m}^2\) \(\therefore\ \text{Area of lawn}\) \(=100-28.27\dots\) \(=71.72\dots\ \text{m}^2\) \(\Rightarrow B\)
