Answer:

16pi mi

Step-by-step explanation:

The smallest circumference for a given area is that of a circle with that area. The area is given by ...

A = πr²

so we can find r as ...

64π = πr²

r = √64 = 8 . . . . miles

The circumference of this circle is ...

C = 2πr = 2π·(8 mi) = 16π mi

The circumference of the area is at least 16π miles.

_____

If the shape is not constrained to a circle, the circumference can be anything you like.

Which points are collinear with A and N?

stepan [7]

Collinear points lie on the same line. So, you must look for other points that lie on the line that connects A and N. If you start from A and continue along that line, you can see that, after N, you will meet points M and F.

So, those points are collinear with A and N.

378 marbles are blue, and 270 marbles are red

Step-by-step explanation:

The total number of ratio units must be multiplied by 6 to get the total number of marbles. Hence the number of blue marbles is 63×6 = 378, and the number of red marbles is 45×6 = 270.
