Answer:
The area is 452.39
The Circumference is 75.36
Step-by-step explanation:
Prime, because the only number that can go into it are 19 and 1
67% of 1280 is 857.6 substrack it and it's = 422.4
In order to solve that, let's call 845 100%, as we're solving it terms of 845. 845 is 100%, then it follows that 8.45 is 1%.
Now we can see how many 8.45's go into 608, which comes out to 71.95266...%, which can be rounded nicely to 72%
The million doesn't matter.
