Is the perimeter of equilateral triangle T equal to the circumference of circle C ?
(1) The sum of the lengths of a side of T and the radius of C is 9.
(2) The length of a side of T is equal to the diameter of C.
How come the answer is B?
i hope to try n explain....plz correct me if i am wrong...
P=3t where t is the side of the triangle
C=2pir where r is radius...
1. t+r = 9
clearly not sufficient
so 3r = 2pir...definately no...Hence B along is sufficient to tell that the perimeter is not equal to Circumference
Note: Give me kudos if my approach is right , else help me understand where i am missing.. I want to bell the GMAT Cat
