    Assuming they are ALL semi-circles.......you can compute areas of those semi-circles and add/subtract the right amounts.

    Well done. I didn't even think they were semi-circles. Area = BigSemi + 3(small-semis) \[A=((\pi)r ^{2})/2 + 3(((\pi)r ^{2})/2)\] \[A=((\pi)(50) ^{2})/2 + 3(((\pi)(10) ^{2})/2)\]

    312.5pi+12.5*3-12.5*2 =312.5pi+12.5 Is it like this or is it wrong?

    Whoops. My earlier one didn't subtract the 2 small semi-circle cutouts. So my answer above, you only add one semi-circle.
