in this case;
shaded area - non shaded area = area looked for
is that what you didn't get, or do you actually need help solving it
continued;
area of a circle; = pie(r)^2
shows that the diameter is 5. radius is half 5/2 = 2.5
plug in
3.14(2.5)^2 = 19.625
find area of square (l x w)
5 x 5 = 25
subtract 25 - 19.625 = 5.375
round
5.38
