Angela goes to the garden. There is a fountain. A circular with 10 m radius lies alone in the center of a circular park with a 200 m radius. Calculate the total walking area to the park visitors.

idk

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
