Hey there!
B in a slope intercept form equation is the the y intercept. It dictates where the line will cross the y axis, and therefore the line's placement altogether. This is because if there was no y intercept, the line would only be shaped by the slope, and would start at 0.
Hope this helped!
I think it’s x=3 because 3 is the highest number in my eyes
2463.01 would be the area for one circle just
The answer is is 4.2 because the 2 rounds up to 3 and the 3 does not round up the four so four does not round up the 2 so it is 4.2
