The first one, 41% vs 3%. If you scale that up to make it more easy to see what they are trying to represent you could make the larger circle 100%, the total of what the public are assuming. In that case, the smaller circle would be just over 7 (3 x 2.44, seeing as 100/41 = 2.44). Therefore, the red circle should be just over 14 times larger (in area) than the blue one, which looks fine above.
The second one, 27 vs 0.7, we have already covered, but for clarity, would be 100 vs 2.6, ergo 38.5ish times bigger.
The third one, 48 vs 27.8 would be 100 vs 57.9 : 1.7 times bigger.
To elaborate

Still all seems cushdy to me.
