We first calculate the area of the entire pool and the side walk.
Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet
Thus the area of the entire pool and the side walk is obtained as follows:
Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.
Thus the area of the pool is given by:
Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:
