QUESTION - C is a circle with centre D and radius 2 . E is a circle with centre F and radius R . Are there any points common to E & C .
1)Distance from D to F is 1+R .
2)R=3
OPTIONS - A,B,C&D

Answer 1

A
If you know that distance from Dto F is 1+R, you don't need to know the R value because C radius is equal to 2 and this means that the E circle have common points with C

Answer 2

R u sure ruizgeorge

Answer 3

yes, think about it:
If you know that C radius is 2 you can walk from the center towards F by 1 unit and you'll find circle E but you're still into circle C
Do you understand me?
