16 model airplanes on his shelf
4 times as many model airplanes as model trains
let's denote the number of model trains as m
So,
m=16×4
m=64
Therefore,there are 64 model trains.

Answer:
The radius is 12.5.
Step-by-step explanation:
The volume of a cone is found using the formula 
. Substitute the values V = 1309 and h = 8. Solve for r.
The interior angles of a triangle all add up to 180 degrees.
You know two of those angles. They are 26 degrees and 90 degrees. The little square thingy in the corner means that angle is 90 degrees.
Using the info above, you can set an equation for the missing angle INSIDE the triangle. Please keep in mind, the x in this equation does not represent angle L.
26+90+x=180
116+x=180
x=64
Now that we know the missing angle inside the triangle, you can find angle L. Angle L and the angle we just found are supplementary, because they are on a line. Supplementary means they add up to 180 degrees.
So, you can make an equation.
64+L=180
L=116
Angle L is 116 degrees. Sorry for the long answer!
