You want to install a 2 yd wide walk around a circular swimming pool. the diameter of the pool is 17 yd. what is the area of the walk? use 3.14 for π.
area of a circle A=r*r*3.14 we have a diameter but we need radius for the formula so what's the radius r=d/2 so r=17/2=8.5yd the area=8.5*8.5*3.14 area=226.86yd sq
