Everything about number one is because it's a half of circle so its area = 1/2 ¶r^2 and its perimeter = ¶r
You will get the incorrect answer because lining up the digits when adding or subtracting is important but it isn’t needed for multiplying.
The answer would be 200,000.
This is because you go to the hundred thousands' place and look one place to the right. Since there is a 6 and 6>5 you round up to 2 making it 200,000. Hope this helps!
