I don't understand how to solve this problem. Please explain and show me how stepbystep. tHANK YOU!

You need to find the diameter of each pie.
You know the area.
A = pi * r^2
50.24 = 3.14 * r^2
50.24 / 3.14 = r^2
16 = r^2
4 = r
Each pie has a diameter of 8 inches. 
wait then what is the 4 for? please explaina little more

r = 4 means the radius equals 4 inches.
The diameter is twice the radius.
