A = \pi r^{2} is the equation used for determining area from radius.  We're given diameter, so to get the radius simply divide by 2. 19/2 = 9.5.

A = (3.14)(9.5)^{2}, when solved, equals 283.385 m^(2).  After rounding to the nearest tenth, we get 283.4 m^{2}

Quincy is going on a vacation to Australia. His flight leaves at 9:50 A.M. It takes 20 minutes to get to the airport, and Quincy
ikadub [295]

If it takes 20 minute to get to the airport, and he wants to be there an hour and 5 minutes before his flight leaves, we have to subtract the time he leaves (9:50) by 1 hour and 5.

9:50 - 1 hour and 5 minutes.

9:50 - 65 minutes.

9:50 - 65 = 8:45.

Which means he must be at the airport at 8:45.

BUT,

The question is asking for the latest time that Quincy can LEAVE for the airport, which means it's 8:45 - 20 minutes, since it takes 20 minutes to get to the airport:

8:45 - 20 = 8:25

Reasoning point F lies on EG and point M lies on EN. If F,E, and M are collinear, what must be true of these rays.
almond37 [142]
This means that all of the points are co-linear. This is because if EG is a segment that contains F, and EN is a segment that contains M, then there can be two different segments. However, for a point F on the first segment and a point M on a second segment be in the same line as an end point of one of the segments, the segments have to be co-linear. They overlap.
