What is the circumference of circle O?
(1) The circle inscribes a square.
(2) The perimeter of the square is 10.
Statement 1: The circle inscribes a square
No information about the radius.
INSUFFICIENT
Statement 2: The perimeter of the square is 10
No information about the circle.
INSUFFICIENT
Combining both Statements:
Perimeter of square inside a circle = 10
Hence side of the square = 2.5. Diagonal =\(\sqrt{2}\)*2.5
Diagonal of the square = diameter of the circle = 2*radius.
We can calculate the circumference if we have the radius.
SUFFICIENT
Correct Option: C
