A circular pool has radius 4.3 meters. You want to build a walkway all the way around it, with a width of 0.6 meters. Estimate the area of the walkway (to the nearest tenth of a square meter).

    So you have a circle with radius 4.3 which is inside a circle with radius 4.6. So find the area of both and subtract the smaller area of the walkway and then make sure to round correctly.
