In the figure above, point R lies on segment OP. The area of the circle with center O is 4(pi), and the area of the circle with center P is 100(pi). What is the length of segment RP?
Put the figure in the comments.

The choices are:
A) 10
B) 8
C) 6
D) 4
E) 2
The areas tell you the radii, so OR = 2 and PO = 10. A little subtraction tells you that RP = 8.
