I don't get this question, can someone please explain it, thanks.
Heres the question: A lighthouse beacon can be seen 24 mi in all directions. What is the area over which the beacon can be seen?
 I think it's circumfrence, but I don't really know what to do.
Thanks, Bob.

The lighthouse beam is the radius of the circle. Since it can be seen for 24 miles, the radius is 24 miles.
The question asks for the area. To find the area of a circle we multiply:
A = pi * r^2
A = 3.14 * 24^2
A = 3.14 * 576
A = 1808.64 square miles
