ummmhh, find the area of each circle, then subtract the smaller from the larger.
area of lighthouse x = 1017.36 mi^2
area of lighthouse z = 2461.76 mi^2
2461.76 - 1017.36 = 1444.4
lighthouse z lights up 1444.4 more area than lighthouse x?
area of lighthouse z = 2461.76 mi^2
2461.76 - 1017.36 = 1444.4
lighthouse z lights up 1444.4 more area than lighthouse x?
correct!!
