Ratio: 2:7
2+7 = 9
747 / 9 = 83
83*2 = 166
83 * 7 = 581
166 to 581
2 more 10s then 11 is 31
1 more 10s then 11 is 21
3 more 10s then 11 is 41.
basic math :)
I believe the answer is B
The area of the paper is the amount of space it occupies.
The length of papers around the edge is 1607680 cm
The given parameters are:


The area of the circle head is:

So, we have:

Substitute known values



The length of the paper is then calculated as:

This gives



Hence, the length of papers around the edge is 1607680 cm
